The ecological asset refers to the sum of natural resource value and ecosystem services provided by ecosystem to human beings, which is an important indicator for ecological environment assessment and ecological construction level. Assessment ecological asset for Contiguous Destitute Areas is conducive to the poor areas of ecological environmental protection. Further, study coupling between ecological value of the assets and economic development in poor areas is the basic premise for co-ordinate ecological construction and poverty alleviation. This study took Qinling-Dabashan Region as study areas, and assessed the ecological value of the assets based on quantitative measurement remote sensing method. In addition, this study constructed suitable poor economic evaluation index system from the natural, social and economic development aspects, and evaluated the level of economic poverty of the counties in the study areas. Then, on this basis, this research also built ecological assets-regional economic poverty coordination coupling model, and calculated the coupling coordination degree of ecological assets and regional economic poverty. The results can basically show the actual situation of the extent of ecological assets and economic poverty in the study area. The results showed that the ecological value of the assets in study area was 50.42 billion yuan in 2010 and shrub had the highest ecological value (11.347 billion yuan). For poverty evaluation aspect, the characteristic of natural conditions and other natural factors in the study area are important factors to poverty, and the corresponding social and economic development has brought a significant effect on poverty alleviation. As a whole, the evaluating results of coupling coordination degree indicated that the lower level of ecological assets goes with the lower comprehensive development level of ecological assets and economic poverty as well as the higher level of economic poverty. The ecological assets and economic poverty have symbiotic relationship. This study concluded that improving ecological environment and strengthening management of ecological assets can achieve the goal to reducing poverty in study area and should be added in the policies of poverty reduction. Finally, this research also discussed the interactive mode between ecological protection and poverty reduction in Qinling-Dabashan Region and Support mechanism is put forward from several aspects, which includes Conversion of Cropland to Forest, eco-migration, eco-tourism and ecological construction of cities and towns. This research can provide the reliable guidance for strengthening management of ecological assets and poverty reduction of Contiguous Destitute Areas in Qinling-Dabashan Region.
