The Contrastively Analytical Research Of Cultivated Land Survey Data From Different Sources And The Cultivated Land Quality Evaluation

In recent years,the comprehensive understanding of the soil condition,promoting agricultural structure adjustment,promoting the sustainable development of agriculture,the strengthened protection of cultivated land,utilization and management are the keys to solve the problem of agricultural production,agricultural product quality and food safety,land use and planning and so on.In this study,contrastly researched the changing of agricultural department and the department of land and resources survey data of agriculture and land scale,to confirm the agricultural department and the department of land and resources data can be consolidated and comprehensive utilizated,and to provide real and reliable basis for the soil improvement and protection,efficient utilization of cultivated land resource.In this study,guangxi zhuang autonomous region GuiZhong area M city,A town,the town of B,C,D town are chosed as research object.The contrast research focus is the grade data contrast analysis of cultivated land and cultivated land quality.In the cultivated land data,the agriculture department of arable land of 1893 figure spot,44819.32 hectares,which including 636 irrigation paddy land,7 WangTian land,1227 dry land,23 vegetable land.In the second land survey of arable land 18706,50742.9 hectares,the paddy field 4867,13839 dry land from the Department of land and resources which.Based on the platform of ARCGIS10.2 and EXCEL software,contrasted and anylized the spatial graphics and attributes of the cultivated land data,statisticsed the farmland classification,the quality grade of land parcel number and area differences from the two departments and got the expected results of the comparison and analysis.In the comparison of productivity level and the natural quality of the national level,the grade difference accounts for 71%,the grade two or within two accounts for 96%;of national land usage,less than grade one accounted for 74.3%,the grade two or within two accounts for 96.3%;of national economic level,less than grade one accounts for 73.85%,the grade two or less accounts for 97.15%;The conclusion is that the above level is basically the same as the correlation in the land.The research shows that the agricultural department and the department of land and resources have different emphasis on cultivated land plot,figure number and area differences.But similar grad classification and evaluation of farm land was found in the results of the two departments.The results show that to solidated and utilized the data of the two departments will improve the soil comprehensive utilization efficienc,and make the planning,and the guidance of integrated management of business management to be convenient,intuitive and fast.
