新疆远离海洋、深居内陆、地形封闭、干旱缺水,沙漠戈壁包围绿洲,绿洲呈分散分割状。森林覆盖率1.68%,盆地中心分布着两大沙漠,生态环境脆弱。40多年来,新疆在改造沙质荒漠化、土壤盐渍化、水域治理、中低产田等荒漠化治理中,取得了重大成就,同时,人口也增长了2.9倍,人类活动使生态平衡失调。荒漠化土地总面积79.59×104km2,其中沙质荒漠化面积52.05×104km2;盐碱土总面积847.6×104hm2,现有耕地中31.1%的面积受到盐碱危害;山区云杉林已减少2.3×104hm2,落叶松减少2.4×104hm2,平原林退化更为严重;80%的草场均有不同程度的退化,产草量下降35.4%~75.8%;湖泊较70年代减少一半,耕地土壤肥力下降。根据新疆荒漠化发生发展的特点与原因,总结防治经验,形成有效的防治方法、措施与体系,新疆的荒漠化是可以防治的
Xinjiang far away from the sea, deep inland, closed terrain, drought and water shortage, the desert surrounded by oasis Gobi, oasis was fragmented. 1.68% of forest coverage, the basin center is divided into two deserts, the ecological environment is fragile. For more than 40 years, Xinjiang has made great achievements in reforming the desertification control of sandy desertification, soil salinization, water treatment and middle and low yield fields. At the same time, the population has also increased by 2.9 times and human activities have made ecological balance unbalanced. The total area of desertified land is 79.59 × 104km2, of which desertification area is 52.05 × 104km2; the total area of saline-alkali soil is 847.6 × 104hm2, and 31.1% of the existing cultivated land is salinized; And the larch decreased by 2.4 × 104hm2. The degradation of the plain forest was even more serious. The degradation of grassland in different degrees was observed in 80% of grassland and the yield of grassland decreased by 35.4% -75.8%. The lakes Compared with the 1970s, the soil fertility of cultivated land decreased by half. According to the characteristics and causes of occurrence and development of desertification in Xinjiang, summing up the experiences of prevention and treatment, and forming effective prevention and cure methods, measures and systems, the desertification in Xinjiang can be prevented
