Design And Development Of Replenishing Cultivated Land With Quantity Mass Note Grade Conversion Information System Of Hebei Province

Since the strategy of cultivated land requisition-compensation balance has beenascertained, cultivated land requisition-compensation balance is still at quantity balancelevel, because of the lack of quantitative index. With the accomplishment of farmlandgrading, there are quantitative index to quality cultivated land. So, it is feasible toexecute replenishing cultivated land with quantity mass note grade conversion. Soreplenishing grade conversion study increases the cultivated landrequisition-compensation balance to a quality balance level. At this stage, thereplenishing cultivated land with quantity mass note grade conversion of cultivated landis accomplished in succession by each province. Nevertheless, certain specializedknowledge is required for the operators in the traditional replenishing cultivated landwith quantity mass note grade conversion, calculating by artificial hand, using paper asstorage device. And the calculating process is complicated, which is not convenient forpopularizing the work. In a word, replenishing cultivated land with quantity mass notegrade conversion system of Hebei Province is established to reduce the difficulty andimprove the work efficiency greatly.According to the cultivated land requisition-compensation balance and research anddevelopment of farmland grading, the paper use the achievement of agricultural landclassification to execute quality evaluation of cultivated land requisition-compensationbalance, and propose the conception of replenishing cultivated land with quantity massnote grade conversion system. The attribute database of Cultivated Land Requisition inHebei Province is built though management of process map in farmland grading andediting the attribute. It is proved that utilization quality index have a positive correlationwith criteria grain by arranging the middle result of agricultural land classification. Theattribute database of cultivated land compensation in Hebei Province are built in twomeasures, connecting fluctuate association with the element association and utilizationquality index to regulations of farmland grading. According to the principle of systematicness, practicability, and extension, this paper applies Visual Basic to carry out repeatedexploitation on MAPGIS, connecting the database of requisition and compensation,getting Hebei Province replenish cultivated land with quantity mass note gradeconversion information system in cultivated land requisition-compensation balancethought.Replenishing cultivated land with quantity mass note grade conversion informationsystem of Hebei Provinceis to develop the function of display of space data and attributedata, compilation, export, management and inquiry of the attribute data andrequisition-compensation conversion, consult and browse the soil type map of city and county in Hebei Province, and realize the function of one key calculation, and display theresult of requisition-compensation conversion, and in the end, achieve the automation andintelligent operation.
