摘　　要：通过一些景观生态学指数的计算与分析,对宜春市中心城绿地系统规划前后的景观格局进行评价。结果表明:按生态学原理规划后的绿地斑块数量有了较大幅度的提高,斑块大小分布呈均匀态势,多样性和均匀度有一定的增加,而优势度有所下降,分离度和景观破碎度也有大幅的下降,分维数则有较明显的上升,绿地景观空间格局优化成果明显。Through calculating some landscape indexs,the quantitative analysis on the landscape patterns of the Yichun Central City Green Space System was made.The results indicated that the quantity of green patches increased significantly after the design,the sizes of green patches were well-distributed,diversity and homogeneity increased,but dominance index decreased,separation index and landscape fragmentation also decreased significantly,fractal dimension increased.These characteristics indicate that the optimizing effect of landscape spatial pattern is evident.
