摘要
生态补偿标准的确定是构建区域生态补偿机制的关键问题。以Landsat遥感影像为数据源,提取土地利用/覆被信息,基于地理学的尺度关联与尺度转换视角,综合考虑区域生态系统服务价值与经济发展状况,结合国内外学者对不同生态系统价值的判断,从生态区、市、县3个空间尺度对甘肃省2011年的生态系统服务价值、生态补偿迫切度和补偿额度及其空间差异进行了测算和分析。结果表明:甘肃省生态区中甘南高原和河西山地荒漠生态区应优先获得补偿,沿黄城镇生态区应优先支付补偿;补偿优先级最低的县均为市辖区和矿业县,阿克塞、肃北、玛曲和肃南等生态输出地区应优先获得补偿;嘉峪关、兰州和平凉3个地级市的生态补偿量为负值,需要支付生态补偿金,酒泉、甘南、张掖等市州的生态补偿量为正值,需获得生态补偿。
Standard of regional eco-compensation（ REC） is one of the key issues to establish REC mechanism. Land use / cover data were acquired by using Landsat remote sensing images.From a geographical view of scale relevance and scale transition,this study put forward ecological compensation urgent index（ ECUI） and the model of eco-compensation standard based on ecological value equivalents by taking both the ecosystem service value and the economic development level of different regions into consideration. The ecosystem service value,ECUI and REC standard of Gansu Province in 2011 were calculated and the spatial disparities were analyzed at three spatial scales： ecological zone scale,prefecture-level city scale and county scale. The results showed that Gannan Plateau,Hexi mountain and desert ecological zone should have priority to get compensation,and the urban ecological zone along the Yellow River should first provide compensation. The municipal districts and mining counties had the lowest priority level among all the counties of Gansu. Among all the 87 counties,Akesai,Subei,Maqu and Sunan were high in ecological output,which had the highest level of priority to get compensation. At the prefecture-level,REC values in Jiayuguan,Lanzhou and Pingliang were negative and they should pay REC while REC values in Jiuquan,Gannan and Zhangye are positive and they should receive REC.
