新疆天山、昆仑山麓的山前冲积、洪积扇扇缘,河岸湖滨,以及农业区渠系、水库附近,都有高水位盐渍土的分布:地下潛水面80—200厘米,一米土层总盐量0.4—2.0％,其面积随灌溉的发展而扩大。这类土区的改良,除工程排水、就地扬水、渠道防渗、精量灌溉外,实行林农结合,生物排水也是有效改良措施之一。栽培果树,丰富了林木树种,不仅可以增大生物排水效能,同时还能增加林带收益,扩大食品生产,改善人民生活。
Xinjiang Tianshan, Kunlun foothills alluvial, alluvial fan fan margin, river bank, as well as agricultural area canal, near the reservoir, there are high salinity soil distribution: underground diving surface 80-200 cm, one meter soil Total salt content 0.4-2.0%, its area expanded with the development of irrigation. Such improvement of soil areas, in addition to engineering drainage, in-place pumping, seepage prevention, irrigation, the implementation of integrated foresters and farmers, biological drainage is also one of effective measures to improve. Cultivation of fruit trees, rich tree species, not only can increase the biological drainage efficiency, but also increase the yield of forest, expand food production and improve people’s lives.
