Analysis of suitability evaluation of high standard farmland construction
This paper took permanent basic farmland pattern as the research object,adopt the plot method,analytic hierarchy process(AHP),geographic information system technology(GIS)and weighted summation evaluation model.The suitability of constructing high standard farmland for permanent basic farmland in the study area was evaluated.The results showed that the permanent basic farmland area of the study area was 55.71 km2,and the total area after deduction of analysis and processing was 27.87 km2.The proportion of area suitable for higt starmland construction was 99.7%.Among them,the area of Grade Ⅰ zoning which was very suitable for high standard farmland construction of 0.28 km2,accounting for 1.0%.The suitable construction area of Class Ⅱ zoning was 4.01 km2,accounting for 14.4%.The suitable construction area of Class Ⅲ zoning was 9.64 km2,accounting for 34.6%.The suitable area for the construction of Class Ⅳ zoning was 13.86 km2,accounting for 49.7%;The unsuitable construction area of Class V zoning was 0.08 km2,accounting for 0.3%.This paper evaluated the suitability of high-standard farmland construction based on permanent basic farmland map spots,and the results of suitability classification could provide a reference for the site selection and planned design of high-standard farmland construction projects to a certain extent.
