    In economic development, "The Territorial Planning of Tibet Autonomous Region" emphasized on the double aims-sustainable rapid economic growth and industrial structure adjustment.In addition, the primary industry will be developed steadily, the secondary industry will be developed emphatically, and the tertiary industry will be developed rapidly.According to the theory of industrial economics and our practical research, we find a ruler, that is:the relationship between GNP growth rate and investment increase rate is a positive correlation, and the relationship between GNP growth rate and industrial structure change rate is a negative correlation in certain period.On the present conditions of society, economy, resources, environment and industrial structure in Tibet, we have a detailed analysis on the relationships among regional economic development, industrial structure adjustment and the supporting capacity of investment, the science and technology level of Tibet, quality of labor, recourses, and environment.According to the financial support from both central government and the local government as well as sustainable development principles of population, resources and environment, it would be very difficult to gain the double aims in the same period of time.In addition, the balance of fragile ecosystem in Tibet would be distroyed, and the natural environment in Tibet would be polluted, in case we exploit mineral and other resources on a large scale without planning.It would be a fatal disaster to Tibet.Because of the particular social and natural situations in Tibet, the social and economic development pattern in Tibet should be different from other regions.First, the non-pollution, non-loss and regenerable social and natural resources should be developed, such as Buddhist temples, folkways,forestry and so on.Second, the sustainable natural resources, such as wind energy, waterpower,geotherms, should be developed.The non-regenerable natural resources and those with pollution problems, such as coal, metal and non-metal mineral recourses should be developed at last.Our suggestions are as follows: in Tibet, the primary industry should be developed steadily, the secondary industry should be developed in the advantageous fields of Tibet, and the tertiary industry should be developed emphatically.Also, it is very important for Tibet to develop with coordination of population, resources and environment.

    Based on the boundary effect theory in geography and ecology, this paper discussed the climatic boundary effects resulted from the interaction between Qinling Mountain and Huanghuai Plain systems, and analyzed the main expressions and causes of three kinds of climatic boundary effects that appear in this area.1.Warm slope zone is one of obvious climatic boundary effects distributed extensively in mountain areas.In the join zone between Qinling Mountain and Huanghuai Plain, it is mainly showed by the air temperature, the growth and distribution of plants, soils and human activities, etc..The separation of cold air by mountains on the west and the north of the join zone, slope radiation and advection, etc.were thought to be the main causes of the warm slope zone.2.The steady topographic wind field-cyclonic shear is often formed in this special terrain, and then rainstorm centers are produced which result in the strong precipitation effect in this join zone.Frequent rainstorm, high precipitation intensity and strong precipitation belt (at about 100-200m altitude) are the main shows of the strong precipitation effect.3.The main show of drought effect is the relatively drought-frequent belt formed at about 300-400m altitude in the high hilly areas, with a monthly drought frequency of 6%-17% which is higher than that of plain and mountain areas.The relative rare precipitation belt formed in the high hilly areas, the warm slope zone, the ecotone of the join zone between mountain and plain, and their interactions should be the main causes of this boundary effect.To study the climatic boundary effect of the join zone between mountain and plain, which is a special climatic phenomenon, helps us to obtain a better understanding of the natural resources and environments in the join zone between mountain and plain, which is very important for the valuation and exploitation and utilization of natural resources, and for the prevention and treatment of natural disasters.

    Many kinds of formulas about Mountain Precipitation Vertical Distribution are presented these days.Among them, Fu's formula is the one applied very often.Based on the shortcomings of Fu's formula, Four-parameter Gauss Formula and its computing method are proposed by Jiang Zhongxin.The formula is described as follows.Where, P=a·l-b·(Z-H)1 Pz means precipitation (mm) at the height of z(m) and a, b, c, H are parameters.The computing method he used is to linearize the above equation.Thus,an equation ln(Pz-c)=lna-b.(Z-H)2 is obtained.Then linear regression method is applied to optimize ln(Pz-c).At last,the computing conclusions are compared with those from Fu's formula.There exist some problems in Jiang's formula and its computing method.Firstly, the optimization is only for ln(Pz-c) with respect to (Z-H)2, not for P.with respect to z.Thus, a large error exists.Secondly, the statistical confidence is not strong for the data set used to fit the formula which has not enough observations to estimate four parameters.Thirdly, it is not reasonable to compare conclusions from the four-parameter formula with those from Fu's three-parameter formula.Due to the above problems, three-parameter Gauss formula and its nonlinear regression method are presented by the authors as follows.P=a·l-b·(Z-H)1 Compared to the Jiang's formula, c is omitted for the reason that c means the precipitation at very high spaces and usually it is assumed to be zero.Thus, the statistical confidence is improved due to the fewer parameters when the number of observations is small.And it is acceptable to compare the conclusions from this formula with those from Fu's formula.A nonliear regression method is applied directly to optimize Pz with respect to z.By this way,the precision is improved largely.At last, the three-parameter Gauss formula and its nonlinear regression method have been successfully applied to the analysis of mountain areas'precipitations in China, such as Huangshan Mountain, Emeishan Mountain, Qinglin and Tianshan Mountain.The average relative errors are less than 2.5% and the maximum relative errors are lower than 5.1%.

    In recent years both abroad and at home there appears an idea that owing to scarcity of the water resource and rapid increace of the POpulation in the Middle East and existing of large rivers, such as the Euphrates River and the Tigris River, which are international ones flowing through several countries, the contradictions over the water resource have become more serious among the countries concerned, and a war for water will soon be broken out in the region.In this paper, in which the main rivers of the region, the Euphrates River and the Tigris River, and the countries concerned are considered, a different viewpoint is put forward.First, it is pointed out in the paper that the runoff of the Euphrates River and the Tigris River is relatively rich and the water resources in the countries are not very poor.Then the situation of the water supply in daily life is analysed in the countries of the region, and the result of the analysis shows that no serious problems resulted from the water use of the neighbouring countries exist in daily life water supply in all the three countries Third, the author points out that a POtential for saving water is enormous.In the region water is mainly used to irrigate the crops in the farmland, and basin irrigation is dominant in the agricultural irrigation.Transforming basin irrigation into spray irrigation and drip irrigation will save large quantity of water, though it is very difficult in some countries.Finally, the fact is expounded that over last decades cooperation and compromise rather than confrontation have been adopted to solve their contradictions in water resource.Based on the consideration and analysis mentioned above the paper concludes that although peopie can not definitely say that in any situation the war between the countries concerned absolutely cannot be produced by the water resource problems, it seems that no war for controlling the water resource will take place in the region.Now the Middle East is experiencing a peace process, though it is a tortuous one.Under this situation a war for water resource is unimaginable in the region.

    Montesquieu(Jan.18,1689-Feb.10,1755),an ideologist of the Enlightenment in France in 18 century, published his final and the best work De l'Esprit des Lois in 1748.The work's Chinese version was published in 1961.In the work, the relationships between laws and geographical factors uch as climate and soil are so discussed in a lengthy words from chapter 14 to chapter 18 in volume 3 that Montesquieu was taken wrongly as an environmentalist.It is difficulty to date the time since and to point who expanded the influence of single geographical factor upon the law, which is related by Montesquieu in his work,to the determinant of synthetic geographical environment upon the human.But it is easy to understand, after reading the concerned chapters of his work carefully,that Montesquieu only emphasized the influence of climatic and soil factors upon human and human activities rather than determinative.Furthermore,when discussing the factors influence upon human,Montesquieu considered climate in the same way as other factors.Therefore,Montesquieu is really not an environmentalist.Although some scholars, both the Western and Chinese, had pointed out and corrected the mistake, some people still keep the previous ideas in mind.It is wished that the mistake is no longer continued.
