中文摘要川江流域防护林区森林地面积仅占全区林地面积的44%,而疏林地、灌木林地、未成林造林地、宜林地等尚需抚育或营造的林地占56%,其中宜林地尚有20%。在分析区内林地利用现状的同时,指出了各类林地的主要土壤类型、主要问题及造林或抚育的难易。着重从森林营造和管理角度,提出了相应的保护林地措施。 
英文摘要The Chuanjiang Basin consists of the Minjiang, Tuojiang, Fujiang, Jialingjiang and Qujiang Rivers,covering an area of 157,000km2. In 60,000km2 land for forestry use,forest land has an area of 26, 000km2,accounting for 44% of the total area of land for forestry use;open forest land 8,000km2,for 13%;shrub grove land 11,000km2,for 18%;the afforested land for immature forest 3,000km2,for 5% ;land suitable for afforestion 12,000km2,for 20% ,At present,the problems existing in the development and use of forest land are: 1. the management of forest is extensive and land resources are predatorily utilized; 2. ruin forest for land reclamation,unreasonably use land resources; 3. pay an attention to foresting but neglect tending of woods.accordingly the effect of foresting is poor.To counter the above-mentioned problems, reasonable measures to use and protect forest land should be adopted as follows s 1. continue to decline the arable land which have been unsuitably occupied by farming, recover and enhance forestry production ; 2. speed up the steps of tree planting and afforestation to raise the forest coverage; 3. enforce tending and management of young and medium woods to ensure soils no bare ; 4. give rein to the potential of sparse woods and shrub grove land,and make the most of forest land resources;5. further strengthen the management on forestry policy to make sure of the practice of scientific measures.
