Analysis of ecological benefit of ecological restoration of aquatic-terrestrial everglade from stability of ecological system
|
Abstract:
According to the physical basis of the stability,the stability of ecosystem is divided into the integrity stability and the stability of system structure.The integrity stability describes the ability of a system to resist the environmental disturb,while the stability of system structure shows the ability of the system to counteract the interior disturb.From the view point of stability of ecosystem,the ecological benefit of ecological restoration for the aquatic-terrestrial wetland is investigated.For the first find of stability,biodiversity index,proportion of area for nature reserves,and the rate of disasters are given as assessment indexes,meanwhile,the method to quantify these indexes is given in this paper.The stability of system structure for the aquatic-terrestrial wetland ecosystem is evaluated by energy theory in a relatively exact meathod.Thus,it can be used as a useful method to assess the ecological benefit for the ecological restoration of aquatic-terrestrial wetland.
