Study On The Evaluation Of Ecological Environment And Ecological Construction In Coastal Areas

According to the characteristics and laws of ecological environment in the coastal areas,this article research the evaluation methods of eco-environment in the coastal areas. Through the investigation and monitoring of ecological environment of Dongtai city.It assess the quality and eco-environmental security in Jiangsu Province and analyse the ecological environment and ecological environment vulnerable area in the coastal areas.A clear ecological functional area is formulated. Eco-industry construction environmental protection programmes and resources of the system are developed alse. The achievements as following:1,The study select land marine ecological against index, and land and marine ecological protection index and land and marine natural environment index and pollution load, and people home life, and industrial governance, and land resources, and environmental investment, and forest green, and marine resources, and city governance, related index, Division for target layer, and guidelines layer, and area layer and index layer four a level, construction has coastal areas ecological environment quality evaluation index system.2,The study describes5levels, reviews for:{very good, good, poor, poor}, combined with evaluation index system and evaluation index of different score values R={5,4,3,2,1}.3,The study evaluate ecological environment of Dongtai in accordance with the evaluation model. The results obtained as follows:the natural environment index4.5999,4.5428ecological risk index, index4.4667on ecological protection, comprehensive scoring4.5803. Comprehensive evaluation of ecological environment of Dongtai city, security alert status.4,The study divided eco-functional regionalization in Dongtai city into four:in lixiahe plain ecological functional area, and the beach East ecological function of soil and water conservation ecological functional area, the coastal areas, and coastal seas fisheries ecological functional area. Determine the important ecological functional area2:Thailand and the East River, the tongyu river water channel maintenance area protection of Dongtai and coastal biological diversity and ecological functions. Identifies "five" limits, moderate, focusing on development of regional development, strategic reserve areas, and limited development area, the prohibition of the development zone.5,The achievement introduced a programme of construction of ecological industry system in Dongtai; Dongtai wetlands and biodiversity survey and analysis, and made the focus of protection:coastal wetland in lixiahe and bio-diversity, net of the upper reaches of the river water, agro-ecosystem biodiversity.6,The article study ecological restoration and development monitoring for key resource. Includes:repairing water eco-system, developed Beach ecological economic development of eco-economic area, in lixiahe area construction of ecological economic development zone, UN-Habitat, coastal development and regulation of the land and other regions.
