基于生态系统服务功能价值的湖北省恩施地区生态补偿研究

[目的]对湖北省施恩地区进行生态价值及生态补偿研究,以期充分发挥恩施地区生态资源丰富的优势,为区域生态补偿机制的建立提供理论依据。[方法]依据相关遥感及社会经济统计数据,对恩施地区2000及2010年生态系统服务功能价值当量及2010年生态价值、生态补偿额度和生态补偿优先指数进行计算和分析。[结果](1)恩施地区2000及2010年生态系统服务价值当量分别为7.84×107,5.88×107,10a期间生态当量下降了25.07%;(2)2010年研究区生态价值2.89×1010元,生态补偿优先顺序为:鹤峰县宣恩县利川市咸丰县巴东县建始县恩施市来凤县。[结论]恩施地区生态补偿优先指数与各县贫困村比例、人均生态系统服务功能价值成正相关性,人均生态系统服务功能价值与各县贫困村比例也存在较强的正相关。

A Study on Ecological Compensation Based on Ecosystem Service Value of Enshi Region in Hubei Province

[Objective] It is necessary to study the ecological value and ecological compensation to make full use of the advantages of the rich ecological resources in Enshi area, Hubei Province, in order to provide a theoretical basis for the establishment of regional ecological compensation mechanism.[Methods] Based on the related remote sensing and statistic data, the value of ecosystem services in Enshi area in 2000 and 2010 was calculated, and the ecological value, ecological compensation amount and ecological compensation priority index in 2010 was analyzed.[Results] (1) The total ecosystem service value of Enshi in 2000 and 2010 was 7.84×10⁷ and 5.88×10⁷, respectively. The calculated value equivalent of the ecological service functions in Enshi areas decreased by 25.07% during the past 10 years. (2) The total value of the ecosystem services of Enshi in 2010 was 2.89×10¹⁰ yuan, and the ecological compensation priority order was as follows:Hefeng, Xuanen, Lichuan, Xianfeng, Badong, Jianshi, Enshi and Laifeng County.[Conclusion] There is a positive correlation between the ecological compensation priority index and the proportion of poor villages and the ecosystem value per capita. Similarly, there is a positive correlation between the ecosystem value per capita and the proportion of poor villages.
