    摘要:

    根据江苏省火电类生产建设项目水土流失典型调查资料,运用SPSS与Excel软件,对单位面积土石方挖填量与扰动后土壤侵蚀模数进行了相关性分析,并且定量、定性地研究了火电类生产建设项目各防治分区的水土流失特点和强度。研究结果表明,水土流失防治分区中临时堆土区的水土流失最为严重,平均侵蚀模数达到14747t/(km2·a),为水土流失重点监测和预防区。苏南、苏北不同地貌类型临时堆土区侵蚀强度差异较大。苏北平原沙土区临时堆土区土壤侵蚀强度最大,侵蚀模数达到14392t/(km2·a),苏南丘陵山区其次,均为极强度侵蚀单位面积土石方挖填量与扰动后土壤侵蚀模数存在线性正相关关系,土石方挖填活动对水土流失的影响敏感度大小排列次序为:丘陵山区(苏南)>平原沙土区>丘陵山区(苏北)>一般平原区(苏南)>一般平原区(苏北)。

    Abstract:

    According to the typical survey data of soil and water loss caused by thermal power projects in Jiangsu Province,the author analyzed the correlation of the filling-cutting volume and soil erosion modulus after disturbed using SPSS and Excel software. The characteristics and the intensity of soil and water loss were discussed qualitatively and quantitatively.The result showed that the soil and water loss in temporary bulldozers area was the most serious,and the average erosion modulus reached 14747 t/(km2·a),which should be the key monitoring and prevenlion area.The difference of erosion intensity in temporary bulldozers between different types of geomorphology areas in the north or south of Jiangsu was great.It was the most in plain sandy area(in the north of Jiangsu),which reached 14392 t/(km2·a). The second was the hilly areathe plain sandy area in the north of Jiangsu Province>the hills area in the north of Jiangsu Province>the plain area in the south of Jiangsu Province}plain area in the north of Jiangsu Province.
