安徽省“十二五”期间生态功能区生态功能评价

Study on Ecological Function Evaluation of Ecological Function Region in Anhui Province during the 12^(th) Five-year Period Based on Remote Sensing Technology

[目的]运用遥感技术评价"十二五"期间安徽省生态功能区生态环境功能。[方法]利用2011~2015年安徽省水土保持生态功能区遥感影像,获取土地利用类型解译数据,结合地面调查和统计资料,依据生态功能区生态功能评价系统对安徽省"十二五"期间生态功能区生态功能状况进行动态监测与评价。[结果]2015年潜山县、太湖县、岳西县、金寨县、霍山县、石台县的生态环境功能指数为75.34~81.83,生态功能等级均为优。"十二五"始末相比,岳西县的生态功能变化度为略微变好,其余5个县均为无明显变化。[结论]安徽省生态功能区县域自然生态优越,生态系统承载力高,生态功能稳定,自我调节能力强。

[Objective] The aim was to evaluate ecological environment function in Anhui Province during the period of 12th Five-Year by u-sing remote sensing technology.[Method]Using remote sensing image for ecological function area of soil and water conservation in Anhui Prov-ince from 2011 to 2015, interpreting data of land use type in Anhui Province were obtained.According to ground investigation and statistical data, dynamic monitoring and evaluation of ecological function condition in ecological function region of Anhui Province were conducted by ecological function evaluation system of ecological function region.[Result] The index of ecological environment function in Qianshan County , Taihu Coun-ty, Yuexi County, Jinzhai County, Huoshan County, Shitai County was 75.34-81.83 in 2015, the ecological functions were excellent.By com-parison of the beginning and end of the 12th Five-Year, the change of ecological function in Yuexi was slightly better , other 5 counties had no obvious change.[Conclusion]Results showed that county ecological function region of Anhui Province had superior natural ecology, high carrying capacity of eco-system, stable ecological function and strong self regulating ability.
