苏南丘陵地区土地持续利用模式的建立

对苏南丘陵地区农田生物结构及功能的研究表明，在荒丘荒坡上建立林地、茶园、果园人工草地及新辟鱼塘以形成农牧渔复合农业生态系统．提出土地持续利用的单元模式；丘岗坡地─—林茶果草立体利用，冲田地─—粮、饲、经、肥、作物合理布局，养殖业—猪、禽、奶牛、鱼全面发展．资源利用─—种养加工业配套成龙．在粮食稳产基础上，农林牧副渔收入增长２．３倍，农用土地收入及人均农业收入均增长２．７倍．

Establishmemt or sustainable land use model in southern Jiangsu hilly region

Studies on biotic structure and function of farmlands in southern Jiangsu hilly region show that a compound agroecosystem can be established through afforesting bare hills and sloping lands or reclaiming them into tea garden, orchard and artificial grassland, and excavating fish ponds. An unit model of sustainable land use in this region is formulated as:hills and sloping lands - stereoscopic use for forest, tea garden, orchard and artificial grassland, erraced field- rational distribution of grain fodder, economic and green manure crops, animal husbandry-overall development of pig, poultry, dairy and fish, resource utilization-planting, animal husbandry and primary processing of farm products.On the basis of stabilized grain production. the total income from farming, forestry, animal husbandry. side-line production and fishery is increased by 2. 3 times, both the income from unit land area of agricultural uses and average income per capita from agricultural industries are increased by 2. 7 times.
