Coordination Difference Between Ecosystem Service and Multidimensional Poverty Under Precise Poverty Alleviation Standpoints: A Case Study of Gansu Qinba Mountain Poverty-stricken Core Areas.

It is one of the important strategies for poverty alleviation and development in the new era to promote the ecological protection and the coordinated development of economic construction in poverty-stricken areas, and it is also the base of the foundation of building a well-off society in an all-round way in 2020 as scheduled. Taking Qinba poverty stricken core areas in Gansu as a case, based on the InVEST model, market value method and shadow engineering method, the value of regional ecosystem services, mainly including water yield, sediment retention, water purification, and carbon fixation and oxygen release, were comprehensively evaluated. Based on the multidimensional poverty measurement index system of farmers' households (A), the multidimensional poverty index (B) was calculated with the participatory rural assessment method. On the base of the comprehensive measure of the coupling coordination differences between A and B, the main factors of the coupling coordination differences were analyzed, and the classification guidance strategy were put forward pertinently. Results show that:(1) the ecological services value of the 25 poverty sections in Qinba Mountain Poverty Stricken Core Areas in Gansu was estimated as 1 525.05×10⁸ Yuan. Among them, the carbon fixation value is the highest. The average ecosystem service value of the orchards is the highest, and that of the crop land is the lowest. (2) Among the multidimensional poverty factors of the 25 poverty sections, the poverty on income was the most serious, followed by the poverties on health status, cultural education and social relationship, and the poverty on basic material requirements was relatively low; (3) It can be seen from the analysis of the coupling coordination differences, 9 sections such as Chela, Zangzu, etc. belong to the livelihood capital retarded type with income, social relationship and cultural education to be the main factors which restrict the manifestation of the ecosystem services. 12 sections such as Nanyang, Yacheng, etc. are the ecological assets retarded type. In those sections, the continuous improvement of the multi-dimensional poverty is restricted because of the lack of the high ecological services. For example the woodlands and orchards, and so on. Linjiang, Xinzhai and Daqiao belong to the coordinated development type. Only the Lichuan belongs to the recession disorders type. (4) The classification guidance strategies are put forward pertinently according to differentiated coupling characteristics and constraints, providing scientific reference for the strategic decision of targeted poverty reduction.
