摘要：

城市化过程的典型表现是非建设用地向建设用地的变化过程。区域可建设用地的预测,与人口、城市化、工业化、区域产业结构调整、外资、地价、政策等因素相互关联。在借鉴已有研究成果和研究方法的基础上,综合采用AHP指标层要素分析、GIS空间分析方法中的空间叠加分析等方法,测算和研究大连市可建设用地的等级结构与分布状况。结果表明:在大连可建设用地等级结构中,Ⅰ级可建设用地(丰富)占17.92%,Ⅱ级可建设用地(较丰富)占18.15%,Ⅲ级可建设用地(缺乏)占28.59%,Ⅳ级可建设用地(极缺乏)占35.34%。Ⅰ级、Ⅱ级可建设用地主要分布在濒临渤海、黄海一侧的沿海平原,其次多为零散分布的低地或丘陵谷地等;Ⅲ级、Ⅳ级可建设用地除北部山区的连片集中分布之外,则多呈带状或半环状分布。

Abstract:

The land-use change is a typical manifestation of the interaction between human beings and the nature, and urbanization finds expression in the transformation from non-construction land to construction land. The assessment of the construction land within a certain area is not only closely related to factors such as landform, land surface water, basic/cultivated land, forest land and ecological reserves, but also interrelated with the population, urbanization, industrialization, regional industrial restructuring, foreign investment, land prices, policies and other factors, including both the external expansion of the land for future construction and its internal updating such as the higher rate of the intensive land use. With the acceleration of urbanization process in Dalian, the demand for various types of construction land, represented by urban land, is inevitably in rapid growth. Therefore, the measurement and evaluation of the hierarchical structure and distribution of construction land in Dalian are the foundation and prerequisite for Dalian's economic and social development planning, especially for the urban construction planning, the industrial layout and the land use planning. This article, as an interim result of "Study on the abundance of Dalian city's construction land", starts from the previous findings and employs a variety of methods such as AHP index layer of factor analysis, the spatial overlay analysis in GIS spatial analysis, and etc. Some conclusions can be obtained as follows. In terms of the hierarchical structure, Dalian's construction land belonging to Grade Ⅰ (abundant), Grade Ⅱ (relatively abundant), Grade Ⅲ (deficient) and Grade Ⅳ (extremely deficient) accounts for 17.92%, 18.15%, 28.59% and 35.34%, respectively. The construction land of grades I & II is mainly distributed in the coastal plain along the Bohai Sea and the Yellow Sea, and the rest is scattered in lowland valleys or hills, etc. The construction land of grades III & IV is mostly distributed in the shape of semi-circle or ribbon, apart from that densely distributed in the northern mountains area.
