These objectives include farmland, forest land, garden land, and grassland. The expected target values of water and soil conservation rate for these areas are calculated for stages in 2030 and 2035. The results indicate that the phased target values for water and soil conservation rates in Yunnan Province are 76.41% in 2025, 78.16% in 2030, and 79.71% in 2035.展开更多
输电线路工程线路长、空间跨度大、扰动分散,造成水土流失呈点状分布,使得布设样点监测输电线路工程的水土保持状况极为困难。以糯扎渡送电广东±800 k V直流输电工程(云南区)为例,利用分层抽样和预监测的方法计算出水土保持监测样...输电线路工程线路长、空间跨度大、扰动分散,造成水土流失呈点状分布,使得布设样点监测输电线路工程的水土保持状况极为困难。以糯扎渡送电广东±800 k V直流输电工程(云南区)为例,利用分层抽样和预监测的方法计算出水土保持监测样点的样本容量,并采用适度法对样本容量进行分配,提出了结合施工现场的输电线路水土保持监测样点布设方案,结果可为同类地区线型工程水土保持监测样点的布设提供依据和参考。展开更多
