Evaluation On Implementation And Benefit Of General Land-use Planning Of Qionglai City

On the basis of socioeconomic statistic material and land-use investigation data, adopting the methods of harmony function, analytic hierarchy process and multivariate-regression, this article analyzes the actuality of land-use, implement situation of last planning, implement benefit and the impact factors that induced the amending of last planning, some conclusions are drew as follows:On the foundation of evaluating the implement situation of last general land-use planning (1997-2010), some ideas can be made out: the implementing power of the planning is more and more light, its solemnity and authority are weakened greatly, and the events of construction project exceeding the index and confines of land use occur repeatedly. The evaluation quantity descended from 85.67 to 73.09, so could drow a conclusion that land-use planning could not be effectively implemented with the time go on, within them the scope of construction land, dimension of farmland, proportion of planning item point were the most obviously index.The evaluation on the implementing benefits of last planning can educe that the planning still had promoted the local socioeconomic development and eco-environmental protection. That is to say, the planning substantially protected the plantation, especially the basic farmland, insured the food safety, and strengthened the power of land's exploitation, reclamation and trimming. This not only meted the balanceable demand of occupying and mending construction land, but also provided balance index for Chengdu and its circumjacent county. What's more, city constructing carried through rapidly, city population increased greatly, and economic level went up rapidly. But with the time go on, The plan's contents often were broke through, the actuality synthesis benefit is higher 5 point than planning synthesis benefit. There into, the economy benefit improved prominence, it's 24 point, the society and ecology benefit corresponding detracted. From evaluation of benefit we could conclude that the main purpose was helping economic developing.The assay consequence of evaluation on implement and benefit can educe land-use planning could not be effectively implemented with the time go on. The impact factors mainly involve four aspects: 1. The quality of planning itself. Including basic data not accuracy, index arrangement not in reason, leadership not take into account, basic farming distribution not in reason. 2. The progress of science and technology. With the improve of labor productivity and the adjustment of estate structure, the capital investment tend to most benefit of land-use, result in the tendencyaccelerate of farming field changing to construction land. 3. The change of policy. From the point of law, our country emphasizes that the compiling and managing the general land-use planning must be strict, the gross and rate of farmland's switching to construction land must be controlled severely and pressingly, and a new construction project must accord with general land-use planning. 4. The development of social economy. The goal of compiling a planning is to ultimately meet the demand of the sustainable development of local social economy. According the rational prediction of plantation and construction land, the quantity of plantation 2010 years is less 9164.87 hm than last land-use planning's quantity, the three requirement quantities of construction land 2010 year are more 8846.33, 7640.27, 6887.32 hm than last land-use planning's quantity. This draws a conclusion by some prediction that last planning is not satisfied with Qionglai's future development unquestionably and must be amended. And if want undertake its availability every planning is better not too long.
