The Application Of Agricultural Land Classification Results In Land Consolidation And Adjustment

As a major part of presenting land resource survey,classification,gradation and valuation on agricultural land can promote the land management from "quantitative management" to "quantitative and qualitative management",it is necessary for land management scientifically.For the districts which have finished the agricultural land grading,how to apply the results enough is obviously important.In view of this,this paper explores the application of agricultural land gradation outcomes in land consolidation and adjustment,taking the land rearrangement project of the Hanjiang of Longmu,LongChuan County in Guangdong Province in China.Firstly,to research the relationship between agricultural land grading and land consolidation and adjustment,including the same and different points.Secondly,according to the requirement of land rearrangement and the features of agricultural land grading,this paper applies the land natural quality grade,land use coefficient,land economic coefficient into the feasibility study,preminary design,quality controlling and project acceptance in the land consolidation and adjustment.Thirdly,taking the agricultural land grading theory as reference,this paper does research in evaluation of cultivated land quality on the agricultural land of Hanjiang of Longmu,Longchuan County after the land consolidation and adjustment.Lastly,this paper does research in cultivated land conversion between grades based on the land use grades.The land consolidation and adjustment is the important source of added arable land.The cultivated land conversion between grades after the land consolidation and adjustment can ensure the balance of arable land truly.It gets some results from the study as follow:(1)theoretical study:agricultural land grading results can offer controlling indicators,evaluation methods and specific evaluation steps for the land consolidation and adjustment,including the establishment of evaluation indicators system,the decision of weight,the land natural quality grade,land use grade,the changes of land grades.(2)Empirical study:agricultural land grading results specifically in the feasibility study,planning design,medium-term check,and acceptance of the land consolidation and adjustment of the Hanjiang part. (3)The evaluation of cultivated land quality results after the land rearrangement in the project district of hanging part in Longmu Town of Longchuan County.(4)The conversion results between grades of the Long Chuan County based on the use grades.
