Abstract

Abstract:

Wetland is one of the most important types in the eco-system.Wetland spatial structure gradually changes over years,as a result of perennial human behaviors and natural process to the wetland directly or indirectly.The change of spatial structure would then directly affect its landscape,biology,and balance and diversity.Human actions in recent years,like water infrastructures,development around wetlands,are all causes of the wetland spatial changes.It appears crucially important to evaluate the spatial change results and the way to search for the relationship between spatial structure evolution and biodiversity.Based on index parameters of spatial structure and diversity,the article states the crucial factors of spatial structure that affects bio-diversity.This article provides an advancing reference for wetland sustainable research and development.

Key words: spatial structure, bio-benefits, index parameter
