摘要
基于系统论原理建立徐闻县海岸带生态承载力指标体系,并采用层次分析法综合评价其生态承载力现状,评价指标权重利用信息熵方法计算,指标权重赋值具有客观性和合理性。评价结果表明:徐闻县海岸带生态承载力为0.17,正处于可载区间的下限,并且发展趋势平缓,可载能力仍有充足空间。如果生态调控措施进一步完善,其生态承载能力将更大。
The index system of ecological carrying capacity in Xuwen County was built based on the system theory. Its ecological carrying capacity was evaluated using the analytic hierarchy. In the model, the weight of evaluating index was defined objectively using information entropy. The evaluating result showed that the ecological carrying capacity was O. 17 in Xuwen County. Its canting capacity is still sufficient, with steady trend. If the measures of ecological regulation are reasonbly optimized,its ecological carrying capacity would be bigger.
