摘要: 在黑河上游实施的以牛羊育肥、退化草原的植被恢复、人工草地建设为主要内容的生态建设, 通过技术集成和试验示范, 效果显著。混播一年生草地平均产干草9.6t·hm2, 每公顷约可为400只羊提供冬春季节补饲用草, 补饲措施可降低牲畜越冬死亡率50%以上, 提高仔畜成活率10%; 围栏封育增加草地水源涵养功能, 可使土壤含水量提高20%左右。绵羊育肥可使示范区农牧民人均增加收入300元。农业结构已经呈现明显的"山地河谷绿洲"一体化发展的系统耦合新结构, 系统耦合的效应对植被的保护起到了很好的作用。

Abstract: Lamb fattening, reseeding grassland and fencing pasture, and fodder cultivation were some main measures of ecological construction in upriver area of Heihe. By technical integration and demonstration, these measures have got observably effect. Average fodder yield of annual sowing grassland is 9.6 t·hm-2 at condition of mixed seeding. The fodder produced from one hectare can supply feed for 400 sheep in winter-spring season. By the fodder supplying measure, the death rate of domestic livestock in winter season can be reduced by 50% or more; the survival rate of lambs and calf can be raised by 10%. On the other hand, soil water content can be raised by about 20% due to the increasing water conservation function of grassland resulted from fencing grassland and stop grazing in growing season. The farmers lived in demonstrate area can increase their income 300 Yuan RMB per capita through sheep fattening. A new farming system, mountain-valley-oasis unitary development, has appeared obviously. The effect of system coupling has lead to a better result of vegetation protection in the area.

Key words: Heihe river, ecological construction, system coupling
