| 摘 要： | 利用武威市四个气象站近五十年各种天气气候资料 ,结合土地资源、人口资源、国民经济发展等特点 ,详细分析了天气气候变化对该区域生态环境的影响 ,提出气候变暖、干旱加剧、上游来水量减少是造成沙尘暴天气发生频繁、土地荒漠化、生态环境恶化的主要自然原因。人口增多 ,对水资源的需求量增大 ,人为的过度垦荒和放牧、乱砍乱伐林木、乱采沙区植物等行为加速了土壤退化的进程。并对该市各县区及我省兰州市、陇南地区的生态环境作了综合对比评价 ,指出改善生态环境的防治对策。

| Abstract: | Using nearly 50 years' meteorological data of 4 stations in WuWei city of GanSu province,combining with land resources,population resources,and local economy development character etc, the weather and climate change influence on entironment in this district were analyzed ;It was pointed out that warming climate, pricking up drought,reducing water from up river are main natural reasons which have resulted in high frequency sandstorms,desertificated land, deteriorated entironment. Increased population,quick increasing water demand,over cultivating wasteland and grazing ,slash woods and digging etc have accelerated the course of soil degeneration.Further, integrated and contrasted analysis on entironment of WuWei city's various town,LanZhou city,LongNan district were analyzed, prevent countermeasures of improving this area's entironment were brought forward. |
