| 摘 要： | 以韩江流域为例，利用1986年与2006年土地利用现状数据．以生态绿当量作为土地利用变化环境影响评价的度量指标．引用生态绿当量数学模型，测算出流域区县各种用地类型的绿当量和区域总绿当量．以此衡量生态环境情况。结果表明：1）1986-2006年，韩江流域及各区县生态绿当量均有所提高,生态环境有所改善；2）生态绿当量作为评价区域生态环境指标具有涵义明确、计算简单方便等优点。

| Abstract: | Taking the Hanjiang valley region as an example,this paper established the ecology green equivalent mathematical model and calculated the value of region green equivalence based on the land-use data of 1986 and 2006.Ecological environment situation was also evaluated,taking ecological green equivalence as the measure index of the environmental impact.The results show that: 1) the ecological environment was improved in the Hanjiang valley region and its counties from 1986 to 2006,so the ecological environmen... |
