The South Bank Of Hangzhou Bay Wetland Landscape Pattern Five Years

Cixi wetland at the south coast of Qiantang River estuary, Hangzhou Bay, close to Hangzhou Bay Bridge, Cixi city suburb, is the North East coast of the Pacific subtropical coastal tidal wetland, is one of the few coastal wetlands. However, long-term high-intensity agricultural development, especially in years of large-scale land reclamation and beach culture, and industrial development and urban construction have made to the Cixi wetland landscape pattern was severely damaged, so that gradually reduced the original wetland, increasing vulnerability of ecosystems, natural character again and again decreasing, growing environmental problems, Cixi wetlands for survival and sustainable development is faced with serious challenges.The purpose of this study is by Cixi wetland landscape pattern and landscape evolution of the situation analysis and the results of the analysis of wetland restoration and protection of constructive comments. Specific guidance is based on landscape ecology theory and methods for the use of three periods Cixi wetlands TM satellite remote sensing image as the basic data sources, remote sensing (RS), Global Positioning System (GPS), geographic information systems (GIS) technology such as 3S under the support of several different periods (2000,2002,2005 years) Cixi wetland landscape pattern classification system, select a series of landscape pattern indices to evaluate the landscape, and focuses on Cixi wetlands and shoreline and deposition, changes in wetlands, the land use changes, analysis of wetland landscape changes in driving forces, revealed the industrial and agricultural production and urban construction, Cixi wetland landscape pattern on what impact, and propose Cixi wetland landscape pattern optimization measures, proposed the development of their unreasonable views of reasonable adjustment.Through Through research that Cixi Wetland Landscape Pattern of the wetlandscape and agricultural landscape, a higher degree of fragmentation, human disturbance significantly. In the 5 years of evolution, the rapid expansion of urban construction land, water, farmland and forest land area decreased, the fragmentation of various landscape elements constantly increased, the overall landscape diversity and evenness decreased. Cixi wetlands in the deposition, the sea coastline all year extension of the wetland area has increased, but growth and slow growth. Industrial and agricultural development and urban construction to reduce the wetlands year after year, to reduce the speed and extent of wetland area greater than the growth rate and growth. Cixi is the man driving the evolution of wetland landscape pattern of the main driving force. Therefore, only by appropriate ecological planning and management, reducing agricultural and industrial development and city construction, will pollute the waters remediation, and occupation of land for restoration to make it revert back to a large contiguous patch to restore original Zhujian wetland landscape, and on this basis, appropriate tourism development, the use of tourism receipts to strengthen the monitoring and protection of wetlands. The ultimate aim is to be able to restore the original Cixi wetland ecological character, as a bright pearl of Hangzhou Bay, Cixi and the pride of the people.
