Based On The Analysis Of Cultivated Land Protection General Plans For Land Use At The County Level Of The Research

The land is the basis of human survival and development of increasingly sharpcontradiction with the people and land of the rapid advance of urbanization,construction, development and farmland protection, socio-economic development andecological environment system, etc.. How the spatial layout of the various types ofland for scientific and rational planning, coordination of land use and naturalecological environment construction, optimizing the structure and layout of urban andrural construction land, and promote land economical and intensive use to ensure thesustainable development of land, overall land use planning the important content.Changes in urban and rural construction land use patterns, based on the Yunnanprovincial government "to strengthen the dam area of cultivated land protectionpromote the mountain urbanization and new requirements to improve the existingland use planning, this paper Dehong State Mans, as the study area.summary andreview of the overall land use planning theories and methods through fieldinvestigation, the Arc Gis for the operating platform, the status quo of land use,existing planning the dam area of arable land protection to achieve the analysis of thecircumstances according to local conditions, and then select the evaluation factors,the use of "extreme conditions" and "suitability index" method of combining landsuitability evaluation analysis of mountain building. Finally, on the basis of theaforementioned study, the development strategy based on the dam area of theprotection of farmland and construction land uphill Mans overall land use planningprogram, Empirical Analysis of adjustment and improvement of Mans arable land andbasic farmland and construction land structure and layout, adjusted planningobjectives and planning the implementation of the key indicators to verify thatimprove the science and operability of the planning program, and for adjustment ofurban and rural construction and development of ideas, to strengthen the dam area offarmland protection, improve the overall land use planning measures recommended.The main conclusions are as follows:1、Mans is a typical mountain city, and the dam area and the mountains ratio isabout nine ninety-one. The current "plan" the dam area of farmland as basic farmlandratio (ie the dam area of arable land protection rate) of68.56%. Mans dam area ofarable land included in the proportion of basic farmland (farmland protection rate) is relatively high, but also required by the provisions and requirements of the YunnanProvince appropriate complement to draw part of the dam area of basic farmland,making the dam area of arable land zoned into the proportion of basic farmland(farmland protection rate) more than80%.2、Mans current planning layout of the dam area of new construction land64.87%, the proportion of mountain gentle slope layout for35.13%. Among them, thenew urban and rural land for construction of the dam area of the layout of theproportion of73.54%, only26.46%of the proportion of mountain gentle slope layout.That focused on the layout of the existing "planning" new rural construction land inthe dam area, the layout is not reasonable, and should be appropriate to improve theproportion of new urban and rural construction land in the mountains gentle slopelayout.3、Mountain building and land suitability evaluation results in the assessmentarea, should be building land area of61,563.37hectares,14337.99hectares of landshould not be built. Should be building sites, one, two, three, should be building sitesand the proportion of12%,28%and60%.4、The Mans gentle slope should be building sites and resources have greaterpotential for development, urban and rural construction land adjustment by adjustingthe urban and rural land for construction layout, and gradually to the mountains gentleslope should be building sites, the dam area of high quality arable land footprint willbe significantly reduced. Show that by adjusting the layout of urban and ruralconstruction land, and strengthen the dam area of farmland protection this initiative isnot only necessary, but also entirely feasible.5、Mans improving this program: refinements and adjustments, regardless of theamount of cultivated land and basic farmland protection area are more than theexisting planning and the top down indicators, urban and rural construction land andnew construction occupation of cultivated land nor exceeded the indicators of higherauthorities. Among them, the dam area of basic farmland protection area of15435.19hectares, complement the program area of3846.52hectares, the dam area of arableland protection rate of81.29%, in line with the provincial government the dam area ofarable land protection rate index (80%); dam area of urban and rural construction landarea of3418.47hectares of new urban and rural construction land area of432.38hectares, respectively, compared with the existing planning a decrease of471.48 hectares,247.73hectares; mountain and rural construction land area of5595.79ha,new urban and rural construction land area of492.80hectares, an increase of2265.60hectares respectively, compared with the existing planning,248.04hectares. Mansimproving land use of the overall planning of the binding targets to achieve better,fully reflects the provincial government to protect the dam area of cultivated land, thespirit of the mountainous and rural construction land layout proportion and relatedrequirements, in line with land use planning requirements.
