Title: Protection and Sustainable Utilization of Wetland at Different Spatial Scales
Abstract: Wetland is very important to environment and human,and it provides the tremendous ecological value,economic value and social value for human.Therefore,stakeholders at the different spatial scales pay the tremendous attention to protection and sustainable utilization of wetland with the idiographic perspective.In the authors' opinion,it is beneficial to research protection and sustainable utilization of wetland at the different spatial scales.This article researches protection and sustainable utilization of wetland at three spatial scales,which are macro scale(region),medium scale(local) and micro scale(enterprise),involving ecological traits,functional traits and human-earth relation of wetland.From macro scale to medium scale and micro scale,it indicates that wetland has the changes from strong ecological stability to weak one and long periods to short one;wetland function changes from adjusting environment to enjoying landscape and providing products;wetland utilization changes from indirect utilization to selective and direct utilization.Therefore,at macro scale,it is pointed out that we should pay attention to inter-region relation,human-earth relation in the region of wetland in protection and sustainable utilization of wetland,and emphasis on sub-area for protection and exploitation of wetland.In detail,wetland area is divided into the restoration zone of wetland,the water and soil conservation zone,the function zone of wetland,the benefit zone of wetland.Furthermore,the function zone of wetland is divided into the forbidden exploitation zone,the control exploitation zone,the restoration zone and the ecological exploitation region.At medium scale it is pointed out that we should care for selection of wetland exploitation patterns and management patterns.In other word,the composing of wetland value is researched by which we can find the reasonable exploitation pattern.And the united management of local government and resident is introduced to attain the sustainable wetland development and balance benefits among the different stakeholders.At micro scale,it is pointed out that we should consider the rational size of wetland exploitation.The rational size of wetland exploitation should be determined by analyzing the carrying capacity of wetland in order to realize the maximal benefits of wetland exploitation.At last,this article puts forward the ecological compensation mechanism and ways of payment for realizing the reasonable protection and the sustainable utilization of wetland at different spatial scales.
