The Research On Ecological Agriculture And Forestry Park Landscape Ecological Evaluation And Plan Base On GIS

In recent years, with the popular of green ecology and the concept of sustainable economic. ecological agriculture and forestry park construction as a new industry is hot with agriculture and tourism development. Studies on landscape ecological evaluation and plan of ecological agriculture and forestry park, explore the ecological evaluation index system, analyze the quality of landscape ecological environment, determine the landscape ecological planning program, is an effective and important way to carry out ecological environment construction and protection of agriculture and forestry park, has an important role in guiding to agriculture and forestry garden's position of the nature and function.With the Anyang, Henan, Pipa temple ecological agriculture and forestry park's landscape planning issues as the basis, use of geographic information systems (GIS)'s overlay technique and combines the analytic hierarchy process and the weighted superposition method, to study the theory, method and process of the agriculture and forestry park Landscape's ecological evaluation and plan. Hope it can establish countermove framework which is for perfect and reasonable environmental protection and ecological construction to achieve the sustainable development of agricultural and forest park.The main contents of the thesis are as follows:(1) It systematic analyzes and summarizes the development of ecological agriculture and forestry park construction process and the existing problems in and out of home, illustrates that the GIS have unique superiority in landscape ecological evaluation and plan of ecological agriculture and forestry park, points out the ecological significance of research.(2) It introduces the methods in practice process for landscape ecological evaluation and plan and understand the application and problems of present landscape ecological evaluation and plan. Taking Pipa Temple ecological agriculture and forestry Park for example, through methods of the literature, collect data, using GIS of superposition technique and analytic hierarchy process and weighted superposition, the thesis builds landscape ecological evaluation index system. Analysis the park's status, generated landscape evaluation picture.(3) According to ecological status of Pipa temple ecological agriculture and forestry park., divided into four ecological function zones, take measures to protect good quality area and restore poor region, coordinate conflicts between park construction and ecological protection.Landscape ecology is a new disciplines developed in mid-19th century, but it has a wide range of applications in land use, environmental remediation, nature conservation, resource development, tourism development, regional plan. With the concept of landscape ecology and sustainable development, depth in plan and construct of agriculture and forestry park, it will bring researchers to a higher level to explore the theories and methods of landscape ecological assessment and plan for agricultural and forest park, provides us a more scientific basis and more effective means. And the application of GIS in ecological agriculture and forestry park's landscape ecological evaluation and plan is a new attempt and inevitable trend.
