山区生态补偿保护成本的空间差异研究
Study on the spatial difference of protection cost in mountain regions
摘要
Abstract
Developing a scientific criterion with spatial difference of Payment for Ecosystem Service (PES) is very important and difficult for the formation of PES mechanism.The spatial difference of the criterion of PES is dependent on the spatial difference of ecosystem services and the cost of PES.The protection cost calculation has been extensively applied in the current studies, because the protection cost can accurately reflect the workload and the contribution of ecosystem conservation.This study contraposes the characteristics of the spatial heterogeneity of the natural and human factors in mountain regions of China, takes Baoxing County, Ya'an City, Sichuan Province as an example, and estimates the protection cost of PES under the support of Geographic Information System (GIS) and statistical data.Meanwhile, accessibility assessment of the protected patches and Areal Interpolation Method is applied to estimate the spatial difference of the protection cost.This study aims to provide reference for the spatial selection and quantitatively setting the criterion of PES.The results indicated that: ①the accessibility coefficient of forest lands is calculated with the road, slope and distance, and it is ranged between 0 and 1, with a mean of 0.18 and the standard deviation of 0.16.② The protection cost of PES in Baoxing County is 459 046 yuan in 2010 and the magnitude order of the investment for protecting different objects is forest land > nature reserve areas > water and soil conservation areas > grass land > water source protected area.③ The protection cost and its components are changed in diverse elevation.Protection cost of forest land is high in 1 000-4 000 m owing to the wide distribution of the forest in the study area.However, protection cost of grass land tends to occur at high elevation (3 000-4 500 m) and the protection cost of water source protected area tends to occur at low elevation (1 000-2 500 m).Accuracy of protection cost calculation and precision of protection cost spatialization depend on the data collection and acquisition of the local ecological construction and protection measures.It is an attempt based on the geographical environment factor for using the accessibility coefficient to adjust the protection cost.The distance, road, slope and direction are mainly considered in the accessibility assessment.However, the personnel factors (such as the traffic tools, the range of vision, and efficiency) and the limit of land use are ignored.关键词
