EVALUATION AND ZONING STUDY OF THE POTENTIAL FOR RESTORING THE FUNCTION OF CULTIVATED LAND IN HILLY AND MOUNTAINOUS AREAS
摘要
Abstract
In order to ensure national food security,it is of great importance to evaluate the functional restoration potential of farmland and to scientifically identify the key areas of the functional restoration potential of farmland.Taking Nankang district,Ganzhou city,Jiangxi province as the study area,and following the research idea of"connotation definition—potential identification—area regulation",15 evaluation indicators were selected from the dimensions of natural resource endowment,location conditions,engineering conditions and economic factors of arable land to be restored,and the TOPSIS model was used to quantitatively identify the key areas of arable land functional restoration potential and their spatial distribution patterns.The results showed that(1)The total area of restored attribute land types in Nankang district was 4 041.02 hm2,mainly dominated by forest land,garden land,water surface of pits and ponds and grassland,with the areas of 1 871.18,1 237.63,892.47 and 39.73 hm2,respectively,accounting for 46.30%,30.63%,22.09%and 0.98%,respectively,and the distribution of restored land types showed a spatial pattern of"high in the middle and,low in the north and south".(2)Based on the CRITICAL-TOPSIS model,the potential index of arable land function restoration in Nankang District was[34.2～92.4],and it was divided into five potential restoration classes from high to low,with the areas of 993.86,1 666.58,1 040.09,309.34,31.15,1 040.09,309.34,and 31.15 hm2,accounting for 24.59%,41.24%,25.74%,7.65%,0.77%of the area of restoration attribute land classes,of which 1-3 potential restoration class land was predominant,accounting for 91.57%.(3)Based on the k-means clustering algorithm with contour coefficients,the restoration potential of arable land was classified into easy to restore,easier to restore and more difficult to restore areas,with areas of 1 782.56,1 101.43 and 1 157.04 hm2,accounting for 44.11%,27.26%and 28.63%respectively,and the areas with higher restoration potential were mainly located in the central,southern and northern parts of the study area.In summary,the delineation of arable land concentration areas or arable land protection cluster areas at the planning level and the implementation of arable land restoration by classified measures can provide a scientific basis for the selection of arable land functional restoration and restoration projects,the preparation and implementation of arable land in/out balance programmes,and is of great significance for the promotion of sustainable use of arable land and the optimisation of the spatial pattern of land.关键词
