A Study on Changes of Ecological Characters and Sustainability of Wetland Ecosystem

Abstract

Abstract: The paper presents all kinds of changes of ecological character and reasons in wetland ecosystem, including changes in wetland area, water condition and quality, unsustainable exploitation of wetland products and introduction of alien species. The index of ecosystem sustainability were shown and measured. The paper also analyses the relationship between sustainability and ecosystem management and ecological restoration.

Key words: cucumber, chilling tolerance, principal component analysis, stepwise regression.
