Soil Productivity Assessment of Arable Land by FMA-AHP in Chengmai County of Hainan Province, China
摘要
Abstract
Geographical distribution evaluation of arable land productivity is the basis of agricultural growth. This is crucial to regional plantation distribution and sustainability of arable land use. An indicator system for assessing arable land productivity was formed, including four sub-goals of soil physicochemical properties, distributions of soil nutrients, site conditions and soil management and eleven indicators. This study evaluated comprehensively the arable land productivities of Chengmai, applying Fuzzy Mathematical Approach to calculate the degree of membership and Analytic Hierarchy Process to determine the weight sum. As indicated in the research, Chengmai ranks middle of arable land productivity and the arable land at the 2, 3 and 4 levels take up 89.8 percent of the total coverage of that area; the geographical distributions of land productivities vary with town locations, wherein, the Ruixi and Jinjiang Town rank top, while either Jiale or Wenru, which has more land of the fifth level, has a lower degree of land productivity. Precipitation and topographical characters can primarily account for the unbalanced geographical distributions of arable land productivity in the study area.关键词
