Ecosystem of the Yangtze River Basin

  • Jin Chen
Chapter

Abstract

The Yangtze River traverses the three great steps of the Chinese geomorphological “staircase.” The climate, geography, and geomorphology in the upper, middle, and lower reaches are very diverse, resulting in rich biodiversity, a large number of rare and endemic species, and a close relationship between the terrestrial and aquatic ecosystems. This chapter describes the characteristics of the ecosystem in the Yangtze River basin through the lens of ecology and environmental science/management. This chapter introduces the major problems of the watershed, which are water pollution, habitat fragmentation and functional decline, overharvesting of wild fauna and flora resources, and invasion of nonnative species. This chapter preliminarily analyzes the history of change and existing conditions of forest cover, the evolution and existing conditions of major lacustrine wetlands, the rare and endemic animals and fish species, and the fishery resources in the Yangtze River basin. Then everything is concluded with a discussion on the structural and integral protection of the Yangtze River ecosystem.
