通过对近5年江苏省典型输变电类生产建设项目进行实例研究分析,探讨不同建设阶段、不同防治分区、不同水土保持类型区条件下的水土流失强度特点,以期揭示江苏省输变电类生产建设项目水土流失特点及规律,为今后的水土流失防治和水土保持监测提供理论依据。结果表明,施工期是水土流失强度最大的建设阶段,塔基施工区是水土流失强度最大的防治分区,丘陵区是水土流失强度最大的水土保持类型区,土壤侵蚀模数分别为5630.00、5920.00、6690.90t/(km2·年),蚀侵级别均为强度。此外,利用EXCEL、SPSS软件,对不同水土保持类型区内输变电项目线路长度与水土流失总量之间的关系进行拟合,结果显示二者之间呈现显著正相关。
In order to reveal the characteristics and regularity of water and soil loss in power transmission engineering in Jiangsu province, and provide a theoretical basis for the water and soil loss control as well as the soil and water conservation monitoring in future, the author explored the characteristics of water and soil loss intensity of the typical power transmission construction projects at various construction stages, in different erosion control areas, and in different type areas of soil and water conservation in Jiangsu province during the past five years. The results showed that the construction period was the construction stage with the strongest soil erosion, tower base construction area was the control area with the strongest soil erosion, hilly area was the conservation area with the strongest soil erosion, their soil erosion modulus were 5630.00, 5920.00 and 6690.90 t/(km2 ~ a) respectively, and their ero- sion intensities were all strong. Besides, it was shown that there was a significant positive correlation between the line length of pow- er transmission engineering and the total amount of water and soil loss by using EXCEL and SPSS software.
