项目摘要
Analysis of land use change based on satellite image and farm household survey in upland area of Sapa, Vietnam revealed that (1) rice terrace expanded and roughly doubled since the 1970s and is still expanding; (2) newer rice terraces are developed on steeper slopes; (3) rice yeilds are not necessarily low in those newer paddies, depending on chemical fertilizer use and amount; (4) ethnic minorities in the area adopted hybrid rice that doubled the yield; (5) cash income from tourism and cardamon sales are contributing to modernization of subsistence farming, in buying seeds, fertilizers and machines; (6) despite rapid population growth of 3% per annum for the last 40 year, agricultural extensification and intensification enabled output growth exceeding the population growth.
基于卫星图像和越南沙巴高地农户调查的土地利用变化分析显示,(1)稻田面积扩大,自 20 世纪 70 年代以来大约增加了一倍,并且仍在扩大; (2)在较陡的山坡上开发较新的水稻梯田; (3)新稻田的水稻产量不一定低,取决于化肥的使用量和用量; (4)当地少数民族采用杂交水稻,产量翻番; (5) 来自旅游业和小豆蔻销售的现金收入有助于购买种子、化肥和机器,促进自给农业的现代化; (6) 尽管过去40年人口每年快速增长3%,但农业规模化和集约化使产出增长超过了人口增长。
