摘要
山区的流域管理某种意义就是生态环境的保护、恢复等,如何衡量水土保持的治理成效,评价水土保持工程措施在多大的程度和多少时间起到生态恢复、生态保护的作用。该文通过利用遥感技术结合通用土壤流失方程(USLE)分析区域水土流失的状况及动态变化,根据分析计算所得的水土流失现状侵蚀图像使小流域水土流失治理范围得到明确,并按土壤侵蚀强度进行分级,为小流域水土流失治理的轻重缓急等方面提供参考。
The design of Guanliang cableway hydrological station on the Luodingjiang River in Zhaoqing has been introduced.And the rationality of choosing cableway main line parameter has been analyzed as well.According to the actual situation of the project, the left bank of the flow measurement section is slope, so it is designed as steel pillars with cable which is suitable.The right bank is a lower, so it is designed as steel tower without cable which is suitable.The cableway with one side backing to the hills another side backing to the ground is Representative.This kind of cableway design provides good representative for relevant engineering design in hydrology cableway design.
