The Study On Agricultural Land Throughput Calculation And Potential Throughput Emancipation

This article take "Agricultural Land Classification and Grading Regulations" (the special purpose of investigation on land resources), "The Throughput Calculation Agricultural Land Regulations", the means of intensive utilization and the theory of regional planning as the basis, and choose the Ningcheng county of Chifeng for the main research region, based on Ningcheng County's region characteristic, we propose the program of agricultural land potential throughput emancipation. That we carry on the plan to this region's agricultural land. Its achievement mainly manifests in the following two aspects:1. The study is based on agricultural land throughput calculation and agricultural land intensive utilizationThis article elaborates three methods of throughput calculation: the theory throughput calculation, the possible throughput calculation, the actual throughput calculation. In order to adjust to the study, the composite throughput is calculated three methods by weighted average way in this study area, and the agricultural land of study area is divided into three areas: the high-quality throughput area, the medium -quality throughput area, the inferior -quality throughput area. And this article Sets up the system of agricultural land intensive utilization that is composed by four constituents: the agricultural land investment intensity, the agricultural land degree of utilization, the agricultural land use efficiency and the agricultural land ecological environment, the four constituents is divided into twelve factors. By this system, the agricultural land of study area is divided into the third-level region, the highly effective intensive utilization area, generally intensive utilization area and inefficient intensive utilization area.2. The scientific planning for agricultural land is solved the question of agricultural land potential throughput emancipationOn the basis of the studies on agricultural land throughput calculation, agricultural land intensive utilization and two different area that is divided, taking two different area superimpose, and applying the land utilization planning district principle of the land utilization master plan. The agricultural land of study area is divided into four areas: the basic farmland centralism area, the general farming developing area, the forest land developing area and the grassland developing area. the basic farmland centralism area includes areas: Xizi,Tianyi,Dashuangmiao,Xiaochengzi,Dachengzi and Sanzuodian; the general farming developing area includes areas: Xizi,Tianyi,Dashuangmiao,Mangnong and Daming. the forest land developing area focus on the neighboring gully; the grassland developing area includes areas: Dachengzi,Xiaochengzi,Sanzuodian,Wuhua,Bisiyingzi and Balihan.
