- 摘要:
- 赣州市水土流失面积1964～1988年呈增长趋势，1988年以后呈减少趋势，章、贡两江输沙量1988年以后逐渐减少，尤其是1998年以来显著减少。事实证明，人为破坏、重治轻防是水土流失加剧的根本原因，预防为主、综合防治是我市水土保持的成功之路。40 a来水土流失与章、贡两江水沙变化态势是赣州市水土保持工作的客观反映。
- Abstract:
- By analyzing the situation of area of soil and water losses in Ganzhou city,which increased in the period of 1964～1988 decreased after 1988,suspended sediment discharge become decreased by degrees after 1988,especially decreased notably since 1998.The fact shows that man-made destruction,emphazing harnessing than prevention are the causes of soil and water loss.Putting prevention first and conducting overall management was a successful way for soil and water conservationin our city.It was on objective reflect of work of soil and water conservation in Ganzhou city that sit uation of soil and water losses and the change of suspended sediment and water of Zhang and Gong River basin withing 40 years.
