摘要
采用模糊综合评价法,选取湿润指数、植被覆盖指数、水体密度指数、土地退化指数、灾害指数作为评价因子,采用专家打分法确定各评价因子权重,利用福建省2006年7-9月67个市(县)的地面气象观测资料和福建省各地土地利用数据,从气象角度对福建省的生态质量进行评价。结果表明:福建省各地生态质量等级均属良好,各地(市)综合评价值介于0.54～0.67,地区间差异较小,这与福建省自身独特的气候、地貌和生物生态环境特征相对应。
Taken the indexes of humid, vegetation cover, water proportion, land degradation and natural disaster as assessment indicators, the regional ecosystem quality was assessed by Fuzzy synthetic method, based on the data of ground observation and land use from July to September, 2006 in Fujian Province. The results showed that the ecosystem quality in the different counties of Fujian Province were all fine. The synthetic values were between 0.54 and 0.67 with small differences, which corresponded with the particular characteristics of climate, physiognomy and ecosystem of Fujian province.
