摘要
城市绿地在改善城市环境、为居民提供游憩服务等方面具有重要作用。目前衡量绿地效果的指标从总量上规定城市绿地应达到的指标，但缺乏绿地空间分布合理性的表征。本文采用景观生态学中的异质性指数和均一性指数，提出判断城市绿地分布合理程度的两种新指标。
The urban Greenland plays an important role in improving urban environmental quality and providing touring service for urban residents.Currently,the targets which judge the effect of urband Greenland only consider the total effect,but they lack the meaning of reseaon abilities of the spatial pattern of Greenland.Therefore,the article puts forward to two kinds of target according to heterogeneity index and homogeneity index by means of landscape ecolaogy.
