从理论、实践和期望3个角度论证了城市绿化斑块存在边缘区域,且存在可被利用的边缘生态效应,这一类型斑块所产生的边缘效应,不仅是绿化建设中不可忽略的一点,同时更应利用这一点为城市绿化规划增加科学性。对现阶段的城市绿化评估报告提出质疑,并提出＂城市绿化生态率＂的评价指标,阐述了城市绿化生态率的量化步骤。同时,将城市绿化与自然保护区的边缘效应进行了对比,得出城市绿化设计的推论,最终得到3条对城市绿化规划的指导意见。
從理論、實踐和期望3箇角度論證瞭城市綠化斑塊存在邊緣區域,且存在可被利用的邊緣生態效應,這一類型斑塊所產生的邊緣效應,不僅是綠化建設中不可忽略的一點,同時更應利用這一點為城市綠化規劃增加科學性。對現階段的城市綠化評估報告提齣質疑,併提齣＂城市綠化生態率＂的評價指標,闡述瞭城市綠化生態率的量化步驟。同時,將城市綠化與自然保護區的邊緣效應進行瞭對比,得齣城市綠化設計的推論,最終得到3條對城市綠化規劃的指導意見。

The existence of marginal areas of urban greening patches from the theoretical,practical and expectational perspectives,as well as the marginal ecological effects which could be exploited were argued.The marginal effect that produced by this type of patches could not only be ignored in the greening construction,but which should be taken advantage of to make urban greening more scientific.Doubt on the assessment survey of urban greening and the assessment indicater of ecological rate of urban greening were put forward and the quantizing steps of ecological rate of urban greening were elabrated.Meanwhile,a comparison between urban greening and the marginal effect of natural conservations was made to make inferences of the design of urban greening,and ultimately three instructive advices about urban greening planning were come up with.
