The Research On Basic Farmland Adjustment In Daqing City

The agriculture is the foundation of national economy, the farmland is agricultural root, while the basic farmland is again the main part of farmland, the foundation that the food produces, therefore protecting the basic farmland is the point that the farmland protects a work, to guarantee a food safety, maintenance society stability, carry out economy society of can keep on development to have very important meaning.But continuously develop because of economic development, the implementation of the point engineering, with as for the basic farmland against will rows into general farmland, so the analysis that adjusts to the basic farmland has important meaning. Adjust the basic farmland of going into, adjusting on the amount and the quality if the balance is treated to a research. This research passes a making use of farmland in Da-qing City and basic farmland present condition characteristics and carries on research analysis to the downtown basic farmland adjustment in Da-qing, mainly is an adjusting of basic farmland; adjust into to carry on analysis respectively. Basic farmland's adjusting is mainly the basic farmland that passes to deduct a present condition right and wrong farmland, the geology disaster area, city planning and village to construct inside the scope, the summary adjusts the amount of a basic farmland 4208.7 hectares.The basic farmland adjusts go into, mainly is《land development sorting programming》and related special subject research that draws up according to Da-qing City and each county result, can increase farmland 5693.2 hectares till 2008, then quality the good farmland adjust into basic farmland, mainly is the main principle that combines basic farmland to divide the line, reference related data, build up farmland in Da-qing City to select the basic farmland evaluation index sign system. Then adopt to analyze a mold piece the concrete value that obtains each index sign according to the GIS data; Make use of layer analysis' method to carry on an evaluation to each farmland quality and make sure that the factor power of each index sign weighs. Pass to make use of folding of GIS to add analysis to alleviate blunt the analysis etc. spaces to analyze the ability of function and processing attribute data, can effectively of the actual circumstance of reaction farmland quality. Pass comprehensive evaluation coefficient method to carry on a quality row preface to the farmland of Da-qing City and finally make sure that the basic farmland amount that select is 4839.22 hectares.According to comprehensive row preface the result and standard food list in Da-qing City produce level establishment model and carry on basic farmland to have to repair balance to investigate and thus get a Da-qing downtown in the process of constructing in, adjust the basic farmland of with adjust go into of the basic farmland has increment in the amount, on the quality, the basic farmland has to repair balance to investigate coefficient<1, is also said to express to plow quality and adjust the basic farmland of basic hold even.Pass the research that adjusts to the downtown basic farmland in Da-qing, can see the basic farmland protection area in an adjustment be no lower than a programming the bottom reaches of the basic farmland protect area; The food from the farmland produced ability with it comprehensive the quality necessarily existed certain relativity of aspect consideration, the downtown in Da-qing basic farmland after adjusting average quality circumstance is basic and adjust an ex- average quality circumstance to have an exaltation; Passing the basic farmland data of adjusting can see, the specific weight of the non- farmland, ascent farmland in the basic farmland after adjusting has to lower, basic farmland after adjusting concentrated even the slice degree also has an exaltation.
