摘要

基于江苏省191个部、省级大中型工程水土流失观测和调查数据

对江苏省点、线式工程水土流失的主要特点进行了分析、结果表明

点、线式工程施工期水土流失量均占到了总水土流失量的90%左右

线式工程水土流失强度(200.00 t/hm

)大于点式工程的水土流失强度(151.37 t/hm

);点、线式工程土壤侵蚀强度均在强度及以上等级;两类工程占地面积与施工期水土流失量均存在线性正相关关系(R

点

=0.9318

线

=0.9439)

且两类工程扰动后土壤侵蚀模数与单位土石方填挖量均存在正相关关系(R

Abstract

Based on the soil erosion data from field observation and survey monitoring in 191 ministerial and provincial level projects

the main characteristics of soil erosion in point engineering and line engineering were analyzed. The results showed that two type projects soil erosion in the construction period accounted for about 90% of the total soil erosion. Line engineering soil erosion intensity(200.00 t/hm2) was greater than that of point engineering(151.37 t/hm2). Line engineering and point engineering were both in intensity and above grade of soil erosion. The quantity of soil erosion and the area in construction period of two type projects had a positive linear correlation(Rpoint2=0.9318

Rline2=0.9439)

soil erosion modulus had a positive correlation with per unit area cut-fill volumes in both type projects(Rpoint2=0.9595

Rline2=0.9324) after the disturbance.
