为了解人为影响下森林景观空间特征的历史变化,应用地理信息系统(GIS)技术研究了溧阳地区森林景观空间格局的动态变化特点。通过计算景观生态学研究用的几个空间特征指标,结果表明破碎度、景观形状指数降低,优势度增大。经综合分析,认为研究区域的森林景观早已逾越了在人为影响下趋于破碎化和异质性提高的阶段,目前在人为的影响下趋于均质性。
In order to understand the historical changes of spatial characteristics of forest landscape under artificial influence, the dynamic characteristics of forest landscape spatial pattern in Liyang were studied using GIS technology. Through the calculation of several spatial characteristic indexes for landscape ecology research, the results show that the degree of fragmentation and landscape shape index decrease and the dominance degree increases. After a comprehensive analysis, it is considered that the forest landscape in the study area has already gone beyond the stages of fragmentation and heterogeneity under the influence of manpower, and is currently under the influence of man-madeness and tends to be homogeneous.
