Abstract


As Urban and Rural Planning Law has come on, it will be a hot issue that how to make unified plan and rationally arrange the layout of urban and rural area. Landscape ecology, which is a new interdiscipline, provides with a new thought as understanding and solving the complicated environmental problem. And breathroughs are also made in the research of urban and rural construction. Therefore, it is of great practical significance to put the theory of landscape ecology into practice, with the purpose of cooridinating the development between cities and the countryside.Based on the principle of landscape ecology, the dissertation, which takes a case of Qingxian County, researches on the dynamics state of landscape pattern in the urban and rural area. The main object of the study is to discusses approaches to apply the concepts of landscape ecology to urban and rural planning, in the event of sharp contradiction between human and environmental resources.The main context for study as follows: the landscape of Qingxian County is classified by means of GIS. Then with the help of FRAGSTATS, this paper analyzes the characters of landscape pattern change in Qingxian County, from two-dimensional analysis of space and time. Principal Components Analysis is used to study the economic drive force, which has great influence on the dynamics state of landscape pattern in Qingxian County, by means of SPSS. It aims to provide a basis for the optimization of landscape pattern in Qingxian CountyThe research results showed that the landscape of Qingxian County consists chiefly of cultivated land. During study time, cultivated land has decrease sharply, as well as garden land and construction area has increased differently. On the one hand, the landscape fragmentation of the whole county increased remarkably, the landscape contagion decreased, and the landscape diversity increased gradually. And the landscape pattern tends to balanced development. On the other hand, the change of landscape pattern between countryside has notable differences. The landscape in Jinniu Countryside has a nice connectivity, and the landscape diversity in Qingzhou Countryside increased obviously. In a word, cultivated land of different counties has decreased, garden land and construction area has increased, and he landscape fragmentation has increased clearly.Finally, through forming green ecological corridor and rationally arranging the layout of green area, the landscape security pattern of urban and rural in Qingxian County has been builded. An optimized spatial design for landscape ecological system in Qingxian County was propsed, in order to improve the environment for human settlement and promote sustainable development between the economy态the society and the environment.
