The Study Of Landscape Patterns Changes And Landscape Ecological Network’s Building

With the speeding up of urbanization, the regional economic and social development are to promote it to a certain extent, but at the same time, a series of urban ecological environmental problems also arises at the historic moment, which seriously threatened the sustainable development of the region. Today, the human activities increasing urbanization,response and slow the ecological environment deterioration problems of urbanization is imminent. Optimizing the regional landscape pattern, construction of regional ecological network has become an effective way to protect and improve the regional ecological environment. The essence of ecological network system building is through regional ecological corridor connecting area relatively dispersed, isolated landscape patches, to form a continuous and complete ecological network, protect ecological system, improve stability,restrict regional landscape ecological system to spread and promote the role of regional sustainable development. Dalian Jinshitan National Tourist Holiday Resort as the tourist town,is a new tourism fast development situation and the combination of the small town construction the new requirements, is undergoing a rapid urbanization process, with strong representation. At the same time, Dalian Jinshitan National Tourist Holiday Resort are faced with how to optimize land use pattern, in order to meet the demand of tourism, afforesting land for residential, industrial, and regional spatial sprawl urbanization cause impact on regional ecosystem function and its ecological consequences such as a series of problems to solve.Taking Dalian Jinshitan National Tourist Holiday Resort as an example, using ERDAS Imagine software to complete video correct, joining together after work, using the Arc GIS software to projection, coordinate the same processing, 1998, 2004, 2009, three images of the space configuration. In Dalian Jinshitan National Tourist Holiday Resort, on the basis of land use status, combining with the characteristics of remote sensing image in the study area, and with reference to the present situation of land use classification for reference standard(GB/T21010-21010), city tourism landscape classification method, rural landscape classification method will be reclassified in the study area landscape.Described by calculating the comprehensive landscape type attitude, study all landscape types in the area in the overall changes in a particular period of time, on this basis, further to asingle type of landscape space change and dynamic attitude to study, with the evolution trend of various types of landscape space at the same time, can realize to the change of landscape type range and velocity measurement. Combining with the status quo and the regularity of spatial landscape pattern in the study area, in order to further implement the landscape ecology network building to provide scientific and beneficial basis.Combining with the landscape spatial pattern characteristics of study area, ecological source is determined, then on the basis of Zhong-xin Chen, etc. Costanza, such as research, to complete various types of landscape ecosystem service function value calculation, to determine the corresponding cost value of landscape types. Generated in Arc GIS software,different time periods in the study area cost figure, for further comparative analysis. On this basis, using the Arc GIS space analysis module calculation for each grid from its recent ecological source minimum cumulative cost, on the basis of the best route to build ecological function networks in the corridor. Finally through the analysis of landscape ecological network structure, complete ecological nodes generated respectively, and the construction of ecological corridors, and finally according to the results put forward the construction of landscape ecology network plan, make each of the elements of the landscape ecology network improved the overall landscape ecological function, promote the landscape structure in the study area, and the species and habitat diversity and stability, the greatest degree to improve its environment, maintain the Dalian Jinshitan National Tourist Holiday Resort of ecological security.
