摘要:

论文以区域农田生态服务价值为基础,以经济发展程度、区域农田生态赤字/盈余与区域提供的生态承载力比值为调节系数,建立农田生态补偿空间转移模型,基于农田生态账户的概念从县(市、区)级层面对武汉城市圈48 个县(市、区)的农田生态补偿空间转移额度进行测算。结果显示:① 武汉城市圈农田生态系统服务总价值为75.00×108元,涉及农田生态补偿空间转移额2.31×108元。② 48 个县(市、区)中,24 个为农田生态支付区,支付区中武昌区的支付量最大,达到5 967.92×104元,最小为14.94×104元(铁山区);24 个受偿区中最大受偿额为238.91×104元(黄陂区),最小为5.14×104元(英山县)。③ 农田生态补偿空间转移量占地方当年财政收入的比例在0.07%~5.24%之间波动。论文提出的农田生态补偿空间转移模型简单、可行,也适用于其他更高或更低的尺度上有农田分布的地区进行农田生态补偿空间转移额度的核算。

Abstract:

Farmland not only provides people with food and material, but plays an integral role in national food security, recreation, biodiversity conservation. The central government has adopted a series of severe policy and mechanism to protect farmland in China. However, due to the huge difference of the economic output of agricultural land and industrial land, the current non-equilibrium farmland protecting policy brings "wipeouts" and "windfalls" to the farmland protecting stakeholders without related compensations. Thus, effective design of farmland spatial eco-compensation has aroused the attention of domestic researchers and government policymakers. Based on their ecological account, this paper established a spatial compensation transfer Model to calculate the farmland spatial transfer eco-compensation among districts in Wuhan Metropolitan Area by combining the methods of ecological services value and ecological footprint/ capacity. The results are described as following: 1) The value of farmland ecological service in Wuhan Metropolitan Area achieved as much as 75.00×108 yuan in 2008, which is quite a huge non-market value that shouldn't be ignored. The district which has the largest value of ecological service is Qianjiang District (6.37×108 yuan), while the least is Jianghan District due to the fact that there is no farmland in this district. 2) For the Wuhan Metropolitan Area, the amounts of districts which are negative in their farmland ecological account is 24, which means there are 24 districts that should transfer farmland spatial eco-compensation to other districts. Among those 24 districts, Wuchang District should pay the largest amount of farmland ecocompensation to other districts (5967.92×104 yuan), with Tieshan District transferring the least (14.94×104 yuan); while the rest 24 districts should obtain farmland eco-compensation. District that should receive the largest amount of farmland spatial compensation is Huangpi District (238.91×104 yuan), with Yingshan County receiving the least (5.14×104 yuan). 3) The amounts of farmland spatial eco-compensation transfer among districts are much lower than their financial income, the proportion of farmland spatial transfer amounts to their financial income varies from 0.07% to 5.24%, so it is realistic to take the farmland spatial eco-compensation transfer measures. In order to protect and enhance the sustainable and variable ecological service supplied by the farmland ecosystem, a reasonable and feasible farmland spatial eco-compensation transfer amounts among different districts should be estimated. Based on ecological account, this paper provided an easy but reliable way to calculate the farmland eco-compensation and its spatial transfer in Wuhan Metropolitan Area by establishing a farmland spatial eco-compensation transfer model, which can also provide guidelines to the calculation of other ecosystem's spatial eco-compensation transfer at different levels.

Key words: ecological service value, Wuhan Metropolitan Area, farmland spatial eco-compensation transfer model, ecological footprint, ecological capacity
