Research On The Demarcation And Protection Of Permanent Basic Farmland In Hulin

As China's industrialization and urbanization degree gradually deepening and deepening,the rapid increase in the level of city,city land sprawl resulting in a large number of high-quality land occupied,destruction and compression of the space of agricultural production and life,has an important impact on the social stability and national food security.Basic farmland refers to the protection of the specific population and social development needs and can not be occupied farmland,which is an important means of rational use and scientific protection of arable land resources.In August 4,2016,the deployment of the full completion of the delimitation of basic farmland and its protection,permanent basic farmland as basic farmland quality is.protected,the strict control of City sprawl of farmland and has positive significance to strengthen the protection of arable land resources.Heilongjiang province is an important commodity grain producing area in China.It is very necessary to scientifically define the permanent basic farmland for scientific utilization and protection of cultivated land resources.Based on the background that national delineation of permanent basic farmland,basic farmland in Heilongjiang Province designated work leading group office issued the notice on accelerating the delineation of permanent basic farmland work notice>notice.The basic farmland protection objectives and tasks assigned to the gradual decentralization,and actively promote the work of permanent basic farmland delineation.Hulin City,as the focus of the eight key verification of a county-level city in Jixi,but also in full implementation of the task assigned to the permanent basic farmland.This paper takes Hulin city of Heilongjiang Province as the study area,based on the Hulin permanent basic farmland planning data and the latest achievements of land change survey data,using ArcGIS platform,planning of permanent basic farmland protection areas of Hulin City,to provide basic reference for further rational and efficient development of basic farmland designated permanent work.The main contents and conclusions of this paper are as follows:Permanent basic farmland demarcated procedures and methods.On the current situation of basic farmland map and data,on the basis of understanding and analysis,in hulin round of general land use planning revision of achievements for reference,go deep into the various township,village practical exploration,collecting hulin arable land and four to the boundary of the status quo of basic farmland,quality,protection of basic farmland responsibility of all relationships and other related information,work in the industry including setting process and scheme,data sorting and processing;Through the land use data,data of basic farmland and urban planning data,traffic data,terrain data,ecological protection from different sources and different formats,different space scale on the basis of data integration,and then establish the evaluation index system of cultivated land to be included in the basic farmland,it is concluded that the influence of the corresponding weight value and through the GIS to analyze influence degree of each factor,determine the basic farmland pieces(blocks)and its spatial layout,to ensure the final demarcation of basic farmland in quantity,quality and layout will satisfy the relevant requirements.Hulin permanent basic farmland delimitation.Hulin the 79710 hm2 delimit of permanent basic farmland,paddy field of 48075.61 hm2,irrigated land 15.32 hm2,dryland 31619.07 hm2,basic farmland protection ratio reached 73%,compared with the last round of basic farmland protection increased by 2%.Delimitation of permanent basic farmland,73.70%of the basic farmland comprehensive index distribution between 0.0498 to 0.2045,the quality of the whole stay at a higher level,and the effects of radiation on selected basic farmland town is larger,the of permanent basic farmland farmland water less than 3000 m distance and traffic arteries in the 1000m,under condition of water resources situation and more superior,the cultivated land quality is relatively good,in addition,the rural residential areas relatively close distance of cultivated land,agricultural production condition is superior,the ease of cultivation and management.Study on utilization and protection of permanent basic farmland in Hulin.Permanent basic farmland from the policy,technology,administrative management and other aspects of continuous improvement of its protective measures.From the policy perspective,governments should stop and deal with basic farmland afforestation behavior,further improve the relevant policies of idle and abandoned development area of basic farmland rehabilitation work,establish and perfect the farmers land protection subsidy system,establish the permanent basic farmland protection fund;From a technical point of view,the protection of permanent basic farmland should be standardized to set up basic farmland protection signs,to protect the responsibility to implement the scientific mechanism,and strive to improve the cultivation of farmers;From the point of view of administrative management,should improve the leadership system of target responsibility government,the implementation of basic farmland protection responsibility,strengthen the efforts to deal with the problem of illegal,timely and appropriate for violations were informed,to play the role of warning,to achieve effective supervision and scientific management.
