摘要
运用模糊概率评价模型,构建岸边带生态恢复适宜性评价指标体系,对北京郊区安达木河岸边带进行了生态恢复适宜性评价,并将适宜性分为:完全不适宜(Ⅰ),低度适宜(Ⅱ),适宜(Ⅲ),非常适宜(Ⅳ)共4个等级。结果表明,安达木河岸边带生态恢复适宜性总体处于Ⅱ和Ⅲ等级之间的过渡阶段,各等级岸边带所占比例分别为10.0%,30.6%,26.7%和11.7%。并在分析安达木河生态恢复适宜性评价图的基础上,针对处于不同适宜性等级的岸边带提出了相应的生态恢复建议。
By means of fuzzy probability assessment model, an assessment indicator system was built to assess the suitability for ecological restoration of Andamu River. The suitability for ecological restoration was divided into four grades： not suitable, low suitability, suitable, and very suitable. Results showed that the total suitability for ecological restoration of Andamu River was between the low suitability and the suitable grade. The proportion of four grades that various types of riparian take up was 10. 0%, 30. 6%, 26. 7%, and 11.7%, respectively. On the base of subsection assessment sketch of riparian zone ecological restoration suitability, ecological restoration suggestions for each grade of riparian zone were brbught forward.
