The Research About The Change Of Cultivated Land Quality Before And After

Cultivated land consolidation as an important way to supplement arable land, on the one hand, can not only increase the area of cultivated land, improve the quality of cultivated land, on the other hand, to achieve dynamic balance of the plow land of also plays a positive role. This study in youxi county of fujian sanming shinyo town comprehensive land consolidation project in 2012 as the research object, evaluation factors and weight mainly use the previous achievements, namely choose Delphi method combined with analytic hierarchy process(ahp) to determine, after the use of ARCGIS to calculate construction of comprehensive scores before and after finishing zone evaluation units, and quality of cultivated land according to the score obtained other division, such as to get the quality of cultivated land before and after the changes.Research results show that shinyo town after comprehensive land consolidation project implementation in 2012, the new cultivated land area of 6.4 hectares, the new state of the cultivated land and don't mainly for 5 to 9, such as natural,Countries use etc are mainly distributed in 8 to 11, etc.,Such as national economy mainly distributed in 8 to 11, etc..By the statistical analysis shows that the main factors influencing the project area of new farmland for effective soil layer thickness and the degree of field road access, suggested that the future can be flat land, increase the effective thickness of soil layer, improve project in the field road access, improve the quality of cultivated land in the new.Shinyo in youxi county town of 2012 comprehensive land consolidation project construction quality of cultivated land area of 121.86 hectares, the construction of the state of the cultivated land and concentration distribution in 5-7, such as nature, of which 5, 6, etc area have increased before the construction, 7, 8, area is reduced, places such as 9 area increased slightly; Before and after the construction of utilization of cultivated land countries are concentrated in 8, 9, places such as eight area increased, September 11, etc are correspondingly reduced; Before and after the construction of arable land, such as national economy are concentrated distribution in 8 to 10, places such as eight area increased, September 11, is the area of small, after construction increased a small amount of 12 area, etc.Area on construction quality assessment factor score of statistical analysis: construction project quality in the quality of the cultivated land plot improve mainly comes from effective soil layer thickness, the terrain slope, irrigation reliability and field road access, this suggests that the land leveling, replace with out-soil measures and appropriate irrigation and water conservancy facilities construction will help improve cultivated land quality.
