【摘要】 根据1990～2000年莆田县各乡镇的耕地年均变化率,人均耕地净减量等指标对其耕地资源作时间上和空间上的分析,由于社会经济发展和人口增长的差异导致研究区中部兴化平原耕地资源流失严重,南部沿海地区耕地资源流失缓慢,而北部山区耕地资源流失最慢的区域差异。在此基础上结合各乡镇经济发展、城镇化程度等其它经济指标采用主导因素法将全县17个乡镇分为4个一级类型:Ⅰ耕地资源严重流失区;Ⅱ耕地资源流失较快区;Ⅲ耕地资源流失缓慢区;Ⅳ耕地资源基本无流失区和7个二级类型,并提出不同类型区存在的问题和应采取的对策。更多还原

【Abstract】 Together with other indexes, the average variation of arable land per year and the net decrease in arable land per capita of Putian County(1990～2000) are analyzed spatially and temporally. The discrepancy of economy development and population growth results in the regional differences including the serious loss in arable land in the central Xinghua Plain, the slower loss in southern coastal area and the slowest loss in northern mountainous area. Combining the above research with some economic indexes and the lead-factor methodology, we can classify the seventeen towns in Putian County into four first-class types(1. region with serious loss of arable land; 2. region with fast loss of arable land; 3. region with slow loss of arable land; 4. region with no loss of arable land as a whole) and seven second-class types. The problems existing in different regions and the countermeasures should be taken accordingly are discussed in this paper too.更多还原
