基于GIS的安徽省会经济圈区域生态补偿优先等级研究

Study on Priority Sequence of Regional Ecological Compensation for the Capital City Economic Circle of Anhui Province Based on GIS

生态补偿已经成为当前全社会所广泛关注的热点问题,补偿优先领域确定是区域协调发展研究的重要内容。利用2007年遥感图像TM数据,对安徽省会经济圈的生态系统服务价值和生态补偿优先等级进行了计算。结果显示:(1)2007年经济圈内六安市所提供的非市场价值总量最大,为5市之首,生态补偿优先等级为六安市>巢湖市>桐城市>淮南市>合肥市;(2)经济圈的六安市为典型的高"生态输出"、经济欠发达地区,应优先享受区域生态补偿。合肥市为高"生态消费"、经济发展水平高,应优先支付补偿。(3)就各市内部而言,市区的补偿优先等级高于周围县域;各县、市区的单位面积非市场价值和生态补偿优先等级差异显著,其中金寨县和霍山县的生态补偿优先级最高。研究结果可为区域生态补偿提供科学依据。

Payment for ecosystem service has received much attention in recent years, and priority sequence of regional ecological compensation is an important part for balancing and coordinating regional development. Ecosystem service value was evaluated by using the Landsat TM data obtained in 2007 on the economic circle of Hefei City, the provincial capital of Anhui Province. The results showed： （1） the non-market value of ecological service was the highest in Lu＇an City, and the descending order for priority sequence of regional ecological compensation was as follows： Lu＇an, Chaohu, Tongcheng, Huainan and Hefei City; （2） on the level of city scale, Lu＇an City was high in ecological output but low in economic development, and it had the highest priority level and should get the first compensation in the City Ecology Circle in Anhui Province, and Hefei City was high in ecological consumption and economic development, and it should firstly provide corn pensation; （3） the differences of non-market service value per unit area and priority sequence of regional ecological compensation were marked among all the 15 counties and urban areas, and the priority sequence of regional ecological compensation was the highest in Jinzhai County and Huoshan County. This study can provide the scientific basis for sustainable development in the City Ecology Circle in Anhui Province.
