The Research Of Land Renovation New Cultivated Land Quality Evaluation Indicator System Optimization And Application

Currently scholars have not carried out evaluation of the quality of arable landwith the platform for quality from scratch during the formation and use of qualityimprovement evaluation of quality in two phases, in the new index system of qualityevaluation of arable land renovation, which can not objectively reflect the inherentrequirements of the objective laws and new arable land renovation, which is one ofthe agricultural sector and land department causes differences in the quality evaluationof new arable land. The study carry out research of the quality of new arable landevaluation indicator system optimization by platform quality on the basis of atwo-stage. This outcome, either to improve the quality of new arable land is less thanthe current evaluation methods, enrich the content of cultivated land qualityevaluation, can also provide a reference with carrying out quality evaluation of arableland renovation work for the new land department, has some theoretical academicvalue and practical significance.The research use expert advice and empirical analysis to select the areas of soil,agriculture, climate, water and remote sensing of14experts by some conference andresearch opportunities. Every round put out14parts, recycling14parts, response ratewas100%, by three times of consulting survey results and analysis, and then, usingSPSS17.0for data analysis and processing. The study includes the following fourareas: the optimization of new arable land quality evaluation indicators; thedetermination of new arable land quality evaluation indicators weight; the standardsof new arable land quality evaluation indicators; selecting a typical case of new arableland area of quality evaluation optimization index system for application verification.The main conclusions are as follows:(1) the construction of arable land qualityshould be divided into platform quality construction and use process of qualityimprovement in two stages, the new arable farmland quality evaluation belongs tothe platform quality construction phase;(2)the optimized indicator system select thefactors of plots conditions, road conditions, slope, drainage conditions, give fullconsideration to the impact of land management factors on quality of new arable land.(3)the optimized index system carried out the application test by an empirical analysis,with Two types of new arable land reclamation by selecting the coastal beaches andmountain hilly slope farmland. The results show that the results of the coastal beachreclamation of arable land in the optimized index system slightly higher than in the pre-optimized index system results, the results of the new farmland mountain hillyslope indicator system under the optimized Top slightly lower than the results in thepre-optimized index system. The optimized index system fully considered arable landrenovation and new features, focus on contiguous farmland quality construction andmeet the development needs of modern agriculture has a positive role in the lead.According to research findings, made the following recommendations:(1)thecultivated land quality evaluation should be carried out in different phases anddifferent sectors. Suggesting the land relevant departments mainly evaluate theplatform quality and the agricultural sector mainly responsible for enhancing thequality of the evaluation phase.(2)Land department of platform quality evaluationshould focus on plots, field road conditions, slope, drainage conditions and otherindicators of factors, the evaluation results are mainly for balance of arable landquality management services; the agricultural sector should focus on the factors aboutpH, N, P, K and other evaluation factors, the results are mainly for agriculturalproduction management services.(3) Should not develop new arable land in a highdegree of fragmentation broken terrain, steep slope, inaccessible land.(4)Proposingdevelop the land renovation new arable land quality index system with the research,scientifically guide land renovation direction and form the “Forced mechanism.”about new land renovation to improve the quality of arable land.
