中文摘要	三峡库区水土流失和面源污染问题严重威胁水库水安全，影响当地的农业和经济社会的发展。通过开展小流域综合治理可有效控制当地的水土流失与面源污染，本文结合绿色流域建设理念，从流域产业结构调整控污减排、坡耕地整治、农业面源污染控制、分散生活污水生态净化和流域自然沟渠及库周缓冲带截留等技术层面，探讨了建立”策源地控制、流通区削减、缓冲带截留”的综合治理体系的模式，分析了当前小流域综合治理和管理中存在的问题，并提出了相应的对策。
英文摘要	Forty eight topsoil ( 0 － 20 cm) samples were collected from four kinds of typical sloping farmlands with horizontal ditch ( HD) ，terrace ridge and bank ( TＲ) ，terrace hedgerow ( TH) ，and none conservation measures ( NC) in Zhongxian County of the Three Gorges Ｒeservoir Area． The surface soil particles，their fractal characteristics and their relationship with each other were studied using fractal dimension． The results showed that there was low volume of clay particles ( 8. 03% － 11. 47%) while high volume of silty particles ( 62. 39% － 83. 24%) in all surface soils on the four kinds of sloping farmlands． The sandy particles in the topsoil on sloping farmlands with HD，TＲ and NC were 22. 95% －29. 58%; however，it accounted for only 5. 29% in the TH sloping farmland topsoils． The volume fractal dimension for the surface soil particles on the HD，TＲ，TH and NC farmlands was 2. 579 － 2. 708，2. 603 － 2. 706，2. 581 － 2. 701，2. 610 － 2. 827，respectively． The mean volume fractal dimension ordered from high to low as TH ( 2. 737) ，HD ( 2. 674) ，TＲ ( 2. 659) and NC ( 2. 654) ． The fractal dimension for the four patterns had significant linear positive correlation with clay particles ( ＜ 0. 002 mm) volume percentage，and had significant linear negative relationship with silty particles ( 0. 002 － 0. 05 mm) volume percentage． However，the fractal dimension for the NC，HD and TＲ patterns was positively correlated to the sand particles ( ＞ 0. 05 mm) volume percentage，while there was no significant correlation between them for the TH pattern．
