中文摘要	长江上游退耕还林战略举措的关键技术之一是要模清该区土壤性状和退化问题 ,进而采取行之有效的土壤退化防治措施。尽快恢复生态 ,保护长江安全。以占该区面积最大的紫色土退化为例 ,提出了该区土壤退化特征、类型和发生现状。指出该区环境的脆弱性和人为干扰是土壤退化根本成因。建议 :( 1 )建立保护区全面封禁管护 ( 2 )构建网格生物篱保持水土增厚土层 ( 3)加强土壤碳氮物质循环强化培肥 ( 4)分带治土造林建立垄沟种植培肥体系等 ,以达到土壤肥力重建 ,取得退耕还林成效
英文摘要	The one of key methods for success in operating the strategy of changing cultivation into tree planting in Changjiang River upstream is as follows. The first is the problem of soil nature and degradation in this region should be understood. Then the available way for preventing soil from degradation will be given out . The ecologic balance should be recovered as soon as possible and the safety of Changjiang should be protected. For example of degradation of purple soil which accounts for the largest area in this region , this paper mentions the characteristics , type and development of soil degradation in this region. The foundamental reason of soil degradation developoment is environmental weakness and human disturbance. On the base of reason above the following methods were putforward : (1) building closed protection and management belt in protection site. (2) constructing network - like biological fence for water soil conservation and soil thickening. (3) strongthening soil material cycle with CPN for fertilization. (4) soil management , afforestation in belt and soil fertilizing system in furrow should be established for reconstructing soil fertility and results of changing cultivation into tree planting.
