Research On The Landscape Ecology Planning Of Nanhu Wetland Park In Tangshan City

Recendy, with the development of urbanization and increasing the city greening area, the resident has satisfied to the request of the amusement place and environment,but the destruction and degradation of wetland bring that the environment function loses and the ecology question is shocking. The Nanhu wetland park of Tangshan city, which founded on the base of the secondary wetland formed by sinking on coal mining, however, the park was exploited unreasonably at present for the reason of deficient understanding on the ecosystem services and led to the breakage of the structure and function of it, reasonable planning park is essential for gaining win-win in the protection and development and promoting the wetland park healthy development. Therefore, this article based on the study of domestic and foreign relevant overview of city wetland park and landscape ecology theory and research status of city wetland park planning, using gps and autocad technical support method, analyse the landscape pattern status,the value of ecosystem services and landscape ecological planning and management measures of Nanhu wetland park in Tangshan city. The result indicated:Analysising the landscape pattern of wetland park show that, the wetland park mainly has eight kind of landscape types and the large plaque type is main. Analyzing from the area, the forest land occupies the dominant position in the entire wetland landscape,the farmland landscape is secondary,the relative area and the average area of waters and building are small, the relative area of the gangue and abandons land are small. Looked from the whole, wetland landscape heterogeneity is general,the fragmentation degree is low,its show that park greening has been achieved some success,but the landscape structure distributes of wetland park is unreasonable, it caused landscape function was degraded serious,it need to assess its main value of ecosystem services,landscape function district and structure adjustment and optimization and make management measures,so that the wetland park to full exert the ecological,social and economic benefits.Integrating wetland resources status and the functional needs of city expansion,the major ecosystem services of wetland park is divided into six areas,its total value of ecosystem services is about 10244.4×10~4 yuan RMB, in which the most important value is material production, which is about 73.33% of the total ones, in the material production value, coal production value is the most,the next value are species habitat,pollution reducing,environment purification,scientific research and education,recreational tourism and adjusting climate. with the constant exploitation,the coal value will become more and more smaller,and the other function value will improve continuously along with the socio-economic development and park planning constructions, in the development utilization and planning management of the wetland park,not because of tremendous economic benefits of coal production to neglect the other important functions, it should be strengthened to improve the city environment, protect biodiversity and provide leisure and entertainment functions for the residents.According to the above analysis results, with the theory basis of wetland park planning, wetland park will be divided into a gallery, a river, the five districts model, and adjust and optimize the landscape structure to each area, based on the original landscape fabric to planning and greening construction.In order to ensure the planning construction of the wetland park carrying on smoothly, working out the management measure of the wetland park. Compliance with the principles of the harmonious coexistence of man and nature and full playing the ecology landscape function and economic efficiency, working out the wetland park management system, regular monitoring the landscape resources,the management of water resources, give fullplay its role in propaganda education base.This article innovation is based on landscape ecology theory, in accordance with the basic process of landscape ecological planning carry on the ecology planing to the wetland park. Through this paper research, not only guiding the healthy development of the Nanhu wetland park in Tangshan city, but also carrying on the preliminary discussion to the planing construction of city wetland park in our courtry, hope that it is important guiding significance to the development and planning of city wetland park.
