- Abstract:
-
Arable land economic potential evaluation is an important part of land consolidation work, which results from the basis of economic benefit appraisal for arable land.Taking Nanhe County Land Consolidation(LC) project of Hebei Province as an example, combining GIS technology,analytic hierarchy process and the parametric method, selecting 9 factors from 5 aspects,i.e.,area,soil,lot,production,traffic, index system,evaluation methods of arable land economic potential and the change in economic valuation based on LC were studied.The results indicate that before LC, arable land was mainly irrigable and dry land and graded 2~3, which occupied 93.84% of the total arable land area.Arable land was converted into irrigable land and grades of arable land economic potential was basically1 and 2 after LC, which occupied 98.51% of total arable land area,and the arable land economic potential has improved 30.53% after LC, the value-added coefficient of the arable land economic potential was 1.305 3 and farmland economic potential has improved 30.53% after LC.The method has instructive significance for arable land economic potential evaluation of LC, and the results may provide scientific basis for economic benefit appraisal of LC project in North China Plain.
