| 摘 要： | 塔克拉玛干沙漠腹地绿地建设长期使用４．０ｇ／Ｌ以上的高矿 化度地下水及生活污水灌溉，对土壤的理化、生化性质产生了重大影响．通过６年的定位试验 观测，数据表明原沙漠腹地风沙土０～２ｍ内可溶性离子总量下降，２ｍ以下增加；土壤粘粒、 有机质含量增加；土壤容重降低；土壤紧实度除表层以外，各层土壤由紧变松；土壤肥力显 著增强；土壤微生物的数量大幅增加，生物活性趋强．

| Abstract: | Because high mineralized groundwater and swage was used to irrigate the artificial greenbelt in the hinterland of Taklimagan desert, physic-chemical and bio-chemical properties of soils changed dramatically. The res ults of the ex- periments of 6 years showed that the contents of soluble ions with in 0-2m decreased and of below 2m increased. The con- tents of clay and organic matter in the soil also increased. The bulk density decreased. Compaction was redu ced except the surface soil. Soil fertility was improved significantly. Soil organisms' activity was enhanced. |
