| 摘 要： | 从江西省现状出发,分析其水土流失特点、森林林分状况、降雨特征、地形地质等自然条件和不合理经营等人为因素的影响,找出河流泥沙和江湖淤积的主要根源。认为花岗岩侵蚀区是主要产沙根源,集中高强度降雨为泥沙搬运提供了动力,地形地势为泥沙汇聚创造了条件,林分、林龄结构不合理,难以保护地表不受侵蚀,不合理经营加速了土壤冲刷和泥沙汇聚。据此,提出了针对性较强的防治对策,为系统研究江西省河湖泥沙提供了依据。

| Abstract: | Based on eco-environmental actuality in Jiangxi province, characteristics of soil erosion and water loss, condition of forest stand, characteristics of precipitation, natural factors of landforms,geology and so on and influences by irrational human activities were analyzed deeply. The results showed that the main sediment resource is granite erosion region, the drive force of sediment yield is provided by concentrated high strength precipitation, sediment concentration condition is created by landforms and topography. The structure of forest stand and age is unreasonable, which can't prevent surface from erosion, and soil erosion and sediment yield were accelerated by unreasonable management. The prevention and control countermeasures aiming at are put forward, which could offer scientific bases to study systematically sediment in river and lake in Jiangxi province. |
