Study On Landscape Ecological Space Optimization Along The South Bank Of Yellow River In Zhengzhou City

The south bank of the Yellow River is an important ecological space in Zhengzhou metropolitan area.With the development of urbanization in recent years,the ecology is becoming increasingly fragile.Compared with other regions along the Yellow River in Henan Province,the relationship between humans and the environment in the region is relatively tense and the conflict between resource development and protection in the region is even greater.According to the requirements of ecological protection,the ecological space protection and ecological functions development along the south bank of the Yellow River should be coordinated to avoid development restrictions due to ecological protection or ecological environment destructions due to development.This is of great significance to regional economic development,industrial structure optimization,the poverty relief in the beach area and the sustainable development of the region.This paper reviews landscape ecology researches,grasps the research methods,combs contents along the Yellow River and sums up experience and deficiency.On the basis of literature review,the landscape ecology assessment and the analysis methods are selected to determine the ecological space optimization schemes.With RS technology and GIS spatial analysis technology as the technology platforms,the landscape pattern indexes are selected to analysis the characteristics of landscape patterns and sum up regional spatial characteristics and problems.The requirement of regional protection is put forward through a regional eco-sensitivity evaluation system constructed to divide ecologically sensitivity partitions.The optimization suggestion of the landscape ecological space structure is also put forward by setting up regional landscape ecological security pattern models.Then the landscape visual quality assessment is adopted to extract the landscape characteristic area.Finally,the landscape ecological space optimization scheme is proposed,including the optimization of landscape ecological structure,the optimization of landscape ecological system,and the guidance of landscape ecological space function partitions,so as to provide reference for the government to achieve regionally sustainable protection and development.
