Study On Landscape Characteristics And Ecological Planning Of Landscape In Zherong County

The subjects of ecology, geography and academics combine the landscape ecology. It is a frame of new concept and an idea of holistic. Landscape ecology is concerned about the landscape spatial patterns, landscape function and landscape dynamic changes. It emphasizes on the maintenance and development of heterogeneity and the importance of scale along the time and space. The urban landscape ecology is a development subject. From the view of ecology, it studies on the center of human activities-cities, and provides the new method for recognizing and solving the urban problems. The urban landscape ecology tries to use the accomplishments obtained in the macro ecology to solve a series of "popular urban diseases" such as traffic, residental, environmental problems caused by the unfit ecological layout of landscape, seeking a way of sustainable development.Based on the analysis of the land utilization figures of Zherong in Fijian Province, the general layout figures of the city and the statistical materials of society and economy, the thesis used the basic theories of landscape ecology, geography and sustainable development with the help of computer and GIS, the author analysed the landscape characters of Zherong in details,and put forward some proposals on the landscape planning and strategies of sustainable development.First, according to the heterogeneity of landscape in Zherong, the author selected the dominant elements such as topography, altitude and climate which reflect the large scale of area differences and the stastistical materials which have long-reaching effects on the county .The county was divided into 8 landscape types: resident and trade area, industry area, traffic land, farmland, garden and greening land, water area, forestry area, unclaimed land .The types have 21 subtypes, the city area, county area,heavily polluted industry area,little maching area,road land,country road land,cultivated land.mushroom land.Taizishen land,tea land,man-made greening land,garden land,reservoir area,river and creek area.defending forestry area, forbid-cut forestry area, bamboo area, economical forestry area,unclaimed mountain, unclaimed land, unclaimed water.Second, according to the characters of landscape in the county, the author put forward a set of assessment indices, which were suitable to little county in mountain. The outcomes of the assessment indicate the conduction of the county is very dangerous. It' s necessary to plan the landscape in the principles of landscape ecology.The thesis used the diversity index, dominance index and evenness index to analysethe landscape patterns in the county, showing the embodying of the spatial characters caused by the man-made disturbance and landscape succession. The thesis also provided the method of the maintenance of the heterogeneity and the conservation of the diversity, because the landscape heterogeneity has a close relationship with the conservation of specis diversityOn the basis of the analysis and assessment of the landscape characters, the author give some suggestions about the method of sustainable development including landscape planning (corridor planning), vegetation planning and the culture study on the landscape planning.The thesis give a direction for the urban sustainable development in Zherong and other little city in mountain throughout the Eastern Fujian Province even the whole country by providing the ecology support and theoretical reference.
