Landscape Ecology Analysing Of Land Sustainable Utilization In The County Area

The subjects of ecology, geography and academics combine the landscape ecology. It is a new concept frame of ecology. Its core of theory concentrative represents on space heterogeneity and ecological holistic, while the idea of holistic is effectively approach for achieving land sustainable utilization. Therefore, the paper combined theories and methods of landscape ecology and land sustainable utilization, used GIS and mathematic statistical methods, analyzed the landscape characters of Chun'an County in details and put forward some proposals on the landscape planning.First, the paper reviewed the research actuality of landscape ecological classification. According to the actual circumstance of Chun'an County, based the administrative unit, artificial interference, landscape factors and function flow for classification principle, the county was divided 3 landscape types,7 landscape subtypes and 18 landscape styles, prepared a good foundation for land use analysis, evaluation and planning.Second, used the space pattern exponential method to analysis the characteristics of landscape pattern of land use in Chun'an County. The research indicated that the land use structure of Chun'an County is main forest and water. The landscape multiplicity and the landscape fragmentation degree are low. The landscape is quite complete, but the landscape complexity and the non-uniformity are low. The land use structure is incompatible.Third, according to the characters of landscape in the county, the paper put forward a set of assessment indices which were suitable for little county in mountain. The outcomes of the assessment indicated the conduction of the county is well. It reflected the land resources of Chun'an County are sustainable.Finally, according to space pattern analysis results and landscape ecosystem evaluation results, put forward a set of reasonable landscape planning project, to provide theories reference for land sustainable utilization of Chun'an County, really coming true the sustainable development of economy and ecosystem environment of Chun'an County.
