云南元谋干热河谷生态环境退化及恢复重建试验研究

干热河谷是我国西南地区的一种特殊生态类型，元谋干热河谷是金沙江干热河谷的典型代表。该区气候炎热干燥、植被稀疏、生态环境脆弱，加之人类活动的干扰，生态环境退化严重。1992年以来，我们对该区的生态环境退化状况进行了研究，并进行了复合生态模式、岩土性质与土壤水分、植被恢复、农（林）业节水技术试验研究和推广。

Studies on Eco-Environment Degradation and the Experiment of Environment Recovering and Rebuilding

Dry hot valley is a special ecological type in southwest China. Yuanmou dry hot valley is a typical model of Jinshajiang River valley. Here, the climate is hot and dry, the vegetation is sparse,and the eco environment is fragile. Under disturbing of human activity, the eco environment degraded severely. From 1992 on,we have studied the degradation status of the eco environment, rock features, soil moisture and vegetation recovering technique. The complex ecological model is established. The technique of water saving agriculture and forestry is also experimented and extended.
