- 摘要:
- 通过对金沙江干热河谷区元谋县人工银合欢（leucaena）治理区与非治理区的土壤理化性质、土壤侵蚀量及林地土壤贮水等方面的研究表明：银合欢作为干热河谷退化生态冲沟治理的先锋树种，具有较好的水土保持效益、很强的水源涵养功能和明显的经济效益，治理区减少地表径流的能力是对照地的5～6倍，减少的泥沙量是对照地的8～9倍，经济产值增加4倍多，并极大地改善干热环境，降低旱季最高温0.93℃，增加空气相对湿度17.15%，为其进一步综合治理奠定了基础。
- Abstract:
- In the Yuanmou River dry-hot valley,the study on the physicochemical properties of soil,water storage capacity of soil and soil erosion amount about the soil and water conservation of the leucaena in controlled area was conducted.The result shows that the leucaena has better function of soil and water conservation and the marked economic effect in the controlled area where has the ecological crisis of Jinsha River dry-hot valley.The controlled area can decrease surface flow by 5～6 times and stream load 8～9 doubles,increased economic 4 times as much as the contrast plot.Also it improved the dry and hot environment and reduced the maximum temperature and increased the air relative humidity,so that established the foundation for continuous comprehensive treatment in rushing gully.
