塔克拉玛干沙漠腹地沙尘暴特征--以塔中地区为例

塔克拉玛干沙漠是中国油气开发的重要区域，沙尘暴是该区域重要的灾害性天气，但以往相关的研究很少。为了了解塔克拉玛干沙漠腹地沙尘暴的发生规律，利用塔中气象站1997-2002年的气象资料，对塔中地区沙尘暴的强度、过程、类型和时间变化等特征进行了分析。研究结果表明：（1）塔中年平均沙尘暴日数为16．83d，较沙漠北缘的轮台和沙漠南缘的民丰、和田为多，体现出沙尘源对沙尘暴发生的影响；（2）沙尘暴发生之前出现明显的风速突然降低和风向转换；（3）同塔里木盆地其它区域一样，塔中沙尘暴也可分为5种类型，其主导类型为冷空气东灌型；（4）沙尘暴时间变化规律明显，且从20世纪90年代至21世纪初，塔中沙尘暴日数与持时明显下降，同全疆的变化趋势一致。     

The greening of brownfields in American cities

The redevelopment of brownfields has become a central component of government efforts to revitalize many US cities. While the focus of these efforts has concentrated on promoting industrial and commercial redevelopment, some cities have started to also consider converting brownfields into parks and open space as part of a more comprehensive renewal strategy. Based on a survey of 20 case studies, this paper identifies and discusses: (1) the primary issues involved in brownfield greening projects; (2) the benefits of such projects; and (3) the specific planning processes involved. The overall conclusion drawn from the survey is that numerous renewal‐oriented benefits can ensue from greening projects, if there is extensive stakeholder commitment devoted to deal with its financial and development‐oriented challenges.
