克拉玛依市南新湿地恢复工程水土流失影响指数计算与评价

Calculation and evaluation of impact index of soil and water erosion in Nanxin wetland restoration project of Karamay City

应用开发建设项目水土保持损益分析理论方法,计算得出克拉玛依市南新湿地恢复工程水土流失影响指数(SWII)为0.282。根据SWII愈小愈好准则,计算得出的水土流失影响指数偏小,因此,该工程的水土流失影响程度较小。

Applying 'soil and water conservation profit and loss analysis of project development and construction' method,the paper calculated the influence index of soil and water loss witch was 0.282.According to the criterion 'SWII as small as possible',this influence index of soil and water loss was small,therefore,the influence of the project on soil and water erosion was less.
