The Study About Method For Planning Of Farmland Consolidation Based On The Theory Of Landscape Pattern

The country vigorously promoted the work since the first land consolidation projects were developed in 2000. Land consolidation effectively increased the area of infield during implement of the activity and is one of important ways for achieving the balance of land occupancy and complementarity. In the process of socialism new rural reconstruction and realization of "the industry to return nurturing to parents the agriculture, the city support the countryside", its importance is reappeared. Land consolidation, a change of the current of land use pattern, will definitely affect the stability of the land ecosystem. Taken up unsuitably, it will wreck the ecosystem, cut down the land production capacity, and affect the sustainable use of land. As land consolidation work thoroughly develop, the studying for the landscape pattern of land consolidation is particularly important. Therefor, on the base of the land development and consolidation project of Weicun Town, Yaodu County, Linfen City in Shanxi Province, this paper chooses the landscape pattern theory as guiding theory and uses ArcGIS to study the method for the planning layout of farmland.This paper includes the following content:①This paper shows the purpose, the method and idea of researching by analyzing the current studying about the land consolidation and landscape pattern;②The land development and consolidation project of Weicun Town, Yaodu County, Linfen City in Shanxi Province, for example, used landscape pattern indices to analyze the current situation of landscape pattern in the project area and find problems existed in Project area of land use Landscape pattern;③Based on landscape pattern theory to construct the decorating standard of corridor and finishing standard of plaques in farmland consolidation;④Used landscape pattern as guiding theory and relied on ArcGIS as a tool to plan farmland consolidation project and finally searched a new way based on landscape pattern theory as the guidance of farmland consolidation planning layout Method;⑤The paper analyzes the influence of landscape pattern resulted from the farmland consolidation by calculating and comparing landscape pattern indexs before and after arrangement of project. The paper reached the following conclusions by studying the above content:①This paper shows that introduced landscape pattern theory to farmland consolidation planning can achieve feasibility of practice;②Replied on ArcGIS software as a means of technology, used DEM model for simulation of terrain of the project area and planned the corridor and plaque eventually, all of these make the planning more scientific and reasonable. The buffer and property analysis functions also provide more technical support for the layout;③Used landscape pattern as guiding theory and Selected the plaque, landscape diversity, landscape architecture and corridor landscape pattern indices to establish the standard of the corridor and plaque, which masked this planning concise and scientific.Moreover, the farmland consolidation planning method has certain extension;④To analyze and compare landscape indices before and after consolidation, the author found that farmland consolidation severly impact on the landscape pattern in project area. The pach number,density,extension index and fractal dimension of project reduced from 107,2.75,5.327,1.065 to 58,1.56,4.524,1.027. The degree of fragmentation reduced from 2.749 to 1.560. The farmland consolidation also enhanced the gallery index. The farmland consolidation conductive to agricultural production, facilitate mechanical work and irrigation of the fields, improve the conditions for agricultural production, and reduce labor costs, which is conducive to raising economic benefit.The innovation points in the paper is to study the method for planning and layout of farmland consolidation from the perspective of landscape pattern, establish the planning standard of corridor and plaques and use ArcGIS as the means to plan and layout. But the studying also has some shortages, for example, selection of landscape pattern indices not comprehensive enough and there are still a lot of planning standard establishment of lacking, we still need greatly improved. Just for the studying of farmland consolidation planning layout method provides a new way of thinking.
