Spatial distribution of ecological compensation based on land opportunity cost: A case study in Zhangjiakou City, Hebei Province

Based on the interests of the farmers of the sloping land conversion program, we propose a calculation method of ecological compensation standard of regional space, so as to provide reference for decision makers. In the qualitative analysis of allocation of compensation, economic and operational feasibility should be taken into account with a series of qualitative factors as the constraint conditions. In the quantitative analysis, the opportunity cost and ecosystem service value, two important factorscompensation distributed in Zhuolu County is the largest and that in Zhangjiakou City the smallest. The amount of compensation of farmland per hectare in Xiahuayuan District is the highest and that in Guyuan County the lowest. The proposed method can solve the problem of “sweeping approach”in ecological compensation for being reasonable and feasible. influencing ecological compensation, were normalized to percentage and considered as weight. By constructing a distribution model based on GIS techniques, the allocation results of ecological compensation were subjected to regional operation and space expression, and the study area was divided into five levels by the clustering analysis. We set the amount of ecological compensation 302.12 million yuan as the goal in Zhangjiakou City, taking counties in Zhangjiakou City as the subjects of distribution, and measured the distribution model of ecological compensation. The results show that the total compensation distributed in Zhuolu County is the largest and that in Zhangjiakou City the smallest. The amount of compensation of farmland per hectare in Xiahuayuan District is the highest and that in Guyuan County the lowest. The proposed method can solve the problem of “sweeping approach"in ecological compensation for being reasonable and feasible.
