Research Of Country Agriculture Land Classification Outcomes Update And Application In Peninsula Hilly Area

Since a long time, the land resource of our country has been in extensive management status, at the same time, with China's urbanization progress, the demand for construction land is increasing, this also intensified agricultural crisis.scientific management and effective supervision of agricultural land has become particularly important. Although our country current laws and regulations for the protection of agricultural land, because of the laws and regulations lag, agricultural land abuse, damage phenomenon is prominent, the agricultural land grain production capacity continues to decline. Agricultural land classification is an important content of the investigation and evaluation of land resources, it is an important symbol of the realization of land management by quantity management mainly to the quantity and quality management of change. With the continuous development of land information technology in the past few years, the agricultural land classification results has become a data base of land management work, and for the agricultural land classification results in the balance of arable land and basic farmland in the division of application have been gradually carried out, which will provide powerful support and guarantee for the protection of farmland, ensure the safety of food production the state, has the vital significance to the healthy and sustainable development of agricultural production.Based on the analysis of extensive data analysis and data, combined with the relevant technical data, taking Zhaoyuan city of Shandong Province as the study area, the agricultural land classification and gradation are studied, and the classification results of agricultural land and its characteristics in the cultivated land requisition compensation balance in the application of exploration and analysis. Based on the in-depth understanding of status of agricultural land area, analyzes on the causes of the agricultural land level changes, and construct different levels based on the cultivated land requisition compensation balance grade conversion coefficient of the system, provide a scientific basis for reinforcing mass balance of cultivated land occupied. The specific content:First, through the collection of base maps and data of agricultural land classification in Zhaoyuan City, calculating Zhaoyuan 2012 agricultural land natural quality index, utilization index, economic index, and in accordance with the relevant technical standards for dividing the agricultural land natural quality grade land,utilization grade and economic grade.Second, analyze the distribution and characteristics of the agricultural land grading results obtained, and with the classification results of agricultural land in Zhaoyuan city in 2006 as the comparison objects, analysis the before and the after area of agricultural land use change, distribution, such as property and its causes, and put forward suggestions on practical problems of agricultural land in Zhaoyuan City.Third, in-depth study of the classification results of agricultural land requisition compensation balance in the application in arable land, arable land accounts for the presence of complement and aiming at the problems in the work of construction, different levels of cultivated land requisition compensation balance level based on conversion coefficient of system, calculation of different grades of cultivated land accounts for the conversion coefficient of complement, provide the basis for reinforcing mass balance of cultivated land occupied.
