摘要
从联合国粮农组织提出的土地资源可持续管理目标出发 ,采用层次分析法 (AHP) ,以西双版纳地区爱尼族大卡老寨为研究点 ,选择 4 1个因素作为参评变量 ,建立区域土地可持续管理评价指标体系。评估结果表明 ,目前大卡老寨的土地经营管理仍处于初步可持续管理的前期阶段。主要因为土地生产力过低 ,其他保护性、安全性、生产性均处于较低水平。作者针对提出了改变土地经营模式等参考建议 :1发展生态农业模式 ,提高土地生产率 ;2应用科技成果 ,提高良种普及率 ;3保护耕地 ,推进规模经营 ;4充分发挥森林的经济、生态和社会效益 ;5提高人口素质 。
This study draws on the FESLM framework developed by FAO, that considers productivity, security,protection, viability and acceptability in evaluating the sustainability of land management. The authors attempt to refine this by proposing a supportive system of 41 indicators, and target values for each that would point to sustainable land management. A comprehensive case study of Daka village in 2002 found an index of 51.23 %, suggesting that its land management is still at a developing stage. The major factors contributing to this low score were: (1) their low productivity to land and labor; (2) land of low and medium productivity is increasing; (3) poor economies of scale; and (4) increasing conflicts over land as the village's population expands. The authors suggest a number of remedial measures in response to these problems. Firstly, more ecologically sound agricultural technologies should be promoted in mountainous areas. Secondly, more problem-oriented research is needed and scientific findings channeled back to improve the sustainability of land management. Thirdly, programs aimed at industrializing agriculture, expanding the scale of land management, and thus increasing farmers′incomes should be expedited. Fourthly, emphasis should be placed on better management of forest resources to more fully exploit their economic, ecological and social benefits. And finally, population growth needs to be strictly controlled, in tandem with programs to uplift the capacity of the villagers.
