摘 要: | 作为元阳水稻梯田农业生态系统可持续性评价的一部分,本文调查了箐口流域梯地的自然生物环境,评价了农业土壤的土壤肥力,采用地质—地貌—土壤信息相结合的方法建立了土壤—景观之间的组合模式。研究确定了人为、气候、地形因素为影响土壤形成的主要因素,评价了土壤潜在生产力以及相关的限制因子,并根据FAO体系,确定并划分了主要的土壤类型。研究结果表明:土壤肥力的空间分布相当均一;土壤属酸性,阳离子代换量和养分储量总体较低;农业生态系统在较大程度上受哈尼群众人为活动的影响,成功维持了相对活跃的养分循环系统。目前的研究集中在:(1) 本研究区域在整个哈尼梯田系统中的代表性评价;(2) 田间水平上的养分循环研究;(3) 土壤特性对作物产量的影响;(4) 将田间水平的研究结果应用于更大的空间单元。

Abstract: | As a contribution to a long-term evaluation of the sustainability of agro-ecosystems in the Yuanyang rice terraces, this paper reviews the bio-physical environment of the terraced landscape in a small catchment around Qingkou village and assesses soil fertility in the village crop growing area. A soil- landscape organization pattern was developed using a geomorphopedological approach. Anthropogenic, climatic and topographic factors were identified as the main soil forming factors. Soil capability and associ... |
