摘　　要：根据广西西江流域的历史农业生产及自然灾害情况，运用系统工程原理和生态经济理论，提出西江流域防护林体系骨干工程的建设建议。重点治理水源涵养区、大中型水库防护区、严重水土流失区、主要江河护岸区、石山岩溶区和主要农业旱区，项目工程实施后，新增加森林面积３７７９４ｋｍ２，减少水土流失７９３．７万ｔ，每年可减少受灾面积５９０１ｋｍ２，年减少粮食损失５．５８亿ｋｇ，减少２．２４亿元经济损失，新增加森林蓄积量２．４１亿ｍ３，折合林价３６９．１９亿元。可提高５０％的抗灾能力。A key engineering construction of sheltering forest system for XiJiang river basin in Guangai is recommended based on the historic agricultural production and natural calamities in the views of systematic engineering and ecological economic. Attention is paid on the recovery of the six major zones such as water conservation zone, big and mid-size reservoir protection zone,water and soil heavy-erosion zone, and agricultral dry zone. The profits of society, ecology and economy are also predicted.
