摘 要: 耕地地力的调查研究是对长江上游地区的生态环境整治建设、农业结构调整等有重要意义的工作。以川江流域及其周边的几个典型农业生态区的耕地为例进行研究,结果表明:采用土壤质量系数、土地生产潜力等对该区域耕地地力进行评价是适宜的。评价结果对该区生态环境建设、农业结构调整等有指导意义。同时,根据该区耕地地力特点和分布状况,提出了保护利用和农业结构调整的对策。 It is important to estimate climatesoil productivity for renovating and constructing the ecoenvironment, and adjusting the agricultural structure. Several typical ecoagriculture areas of Sichuan province in upper reaches of the Yangtze River were studied, and the result showed that: it is feasible to estimate the climatesoil productivity by using the soil quality index and potential productivity as the criterion. Estimation result is of good direction meaning to renovate and construct the ecoenvironment and adjust the agricultural structure. According to the climatesoil productivitys characteristic and its distribution, the countermeasures of renovating and constructing the ecoenvironment and adjusting the agricultural structure were given.
