为了揭示森林生态系统健康状况的发展规律,本研究构建了森林健康评价指标体系,采用复杂网络和综合指数法对森林健康状况进行了评价分析。以广州市大岭山林场216个小班为例,把优势树种和龄组相同的相邻小班合并成景观斑块,构建了小班网络、景观斑块网络,并计算出不同尺度的健康指数。结果表明:小班尺度,优质、健康、亚健康、不健康、病态小班分别是139个、44个、20个、11个、2个;景观斑块尺度,优质、健康、亚健康、不健康、病态景观斑块分别占总面积的75.57%、10.68%、10.13%、2.86%、0.76%;区域尺度,整个区域的森林健康指数为78.62,森林健康等级为健康。研究结果可为森林可持续经营提供科学依据...

In order to reveal the law of development of forest ecosystem health. The indexes system for forest health evaluation was constructed. Based on the system, the forest health status was analyzed and evaluated by using of complex network and integrate index method. The Two hundred and sixteen Sub-compartments of Dalingshan Forest Farm in Guangzhou were taken as the example plots, of them, the sub-compartments with same species and same age groups were merged into landscape patches, and the sub-compartment network and landscape patches network were formed thus the health indexes of different scal...
