The Research On Agriculture Land Productivity Calculation Modeling And The Results Analysis

The task of productivity calculation for agricultural land is based on the gradation resultsof farmland, so as to get a further understood of its comprehensive productivity. The maincontent of this task is to reflect the using status and the development potential of agricultureland by theoretical productivity, achievable productivity and practical productivity. This papertakes Ningshan County as the research object, constructed the liner regression modle ofstandard food’ theoretical yield and natural quality index, the liner regression modle ofstandard food’ achievable yield and using index based on basic data material from NingShanxian. With these regression modles, this article firstly calculated the theoretical yield andproductivity, the achievable yield and productivity of standard food from town domain scalesand county scales respectively. Secondly, the pratical yield and the pratical productivity werecalculated according to statistical data of Ningshan County. Thirdly, this paper calculated thetheoretical and the acheivable intensity and potential of agriculture land use with thecalculation results of the three yields. In order to espress the spatial distribution and thedeveloping prospect of agriculture land use more clearly in each town of Ninshan County, thispaper drew corresponding thematic maps with GIS software so as to evaluate and analysis theAgriculture land productivity. Finally, some targeted suggestions were put forward in the hopeof giving certain reference values for the administration of agriculture land.
