Research On The Evaluation Of Cultivated Land Quality In Land Consolidation Project Area

With the development of urbanization, the land demand of non-agricutural construction increase quickly. A number of cultivated land must be occupied It is important for our country to protect cultivated land In order to balance the total number of cultivated land a effective way is land consolidation or reclamation of old villages, that can improve the degree of land use in quantity and quality. The quantity can be measured, but the quality of land consolidation is hard to measure. So, it is necessary to carry out the quality evaluation of cultivated land It can provide effective suggestions for land management in the future.The paper take the land consolidation project of Changtai county as an example, according to its plan of climate, geology and geomorphology and transportation,using the GIS to determine the evaluation unit by the data of land consolidation project in 2013.Different areas, different indexes, so it is essential to establish a rational evaluation index system. The paper using a new calculation method of coefficient to evaluate. Compare the differences of land consolidation between before and after, analysis the problems in every classification cultivated land, and put forward the improvement measures. It is helpful for Changtai county to develop the high-efficiency agriculture and promote the revenue of landThe main results are:In accordance with the ’Regulations for Classification on Agricultural Land’,the evaluation index is unable to meet the actual situation of land consolidation project. Based on the opinion of experts and the local farmers, the study add three index about the retention capacity of water and fertilizer, the types of water and flatness of field, and verified by T testIt must experience a long time for soil improvement So, the paper use a new calculation method to evaluate land quality. Analysis the average of index, classification and so on. Analyzing the overall quality of cultivated land and the problems in use, then putting forward the corresponding methods. It is a reference for Changtai county to develop the efficient agriculture.
