阿拉尔至和田沙漠公路防风阻沙效应参数分布特征

Efficiency Distribution Characteristics of Wind Prevention and Sand Resistance in Alaer-Hetian Desert Highway

以塔克拉玛干沙漠为研究区域,利用阿拉尔—和田沙漠公路沿线及周围15个气象水文站近50a来(1956—2007年)历史资料,结合沙漠腹部塔中气象站近10a来(1999—2007年)观测资料及近1a(200704—200804)野外科学考察和K127km监测资料,采用气候学、风沙物理学、流体力学、统计学相结合方法,提出沙漠公路防风阻沙效应动力参数:地形地貌、盛行风向、风速;影响参数:温度、沙表面温度、降水量、湿度、蒸发量,分析研究阿拉尔—和田沙漠公路防风阻沙效应环境气象参数分布特征及变化趋势,为沙漠公路未来养护以及生态环境保护提供科学依据。

Taklimakan desert is set as the investigation area. Based on the past about fifty years （1956-2007） datum from fifteen meteorologic stations along and nearby the Alaer-Hetian desert highway, and the about ten years （1999-2007） and another one year （200704-200804） datum from field observation inside the desert, using the method of climatology, physics of wind-blown sand, hydrodynamics and statistics, this paper presents the drive parameters of wind prevention and sand resistance in desert highway, e.g. landforms, geomorphology, wind direction and speed, and its effect parameters, e.g. air and surface temperature, precipitation, humidity, evaporation, and then analyzes the environmental and meteorologic parameter distribution characteristics of wind prevention and sand resistance in the Alar-Hetian desert highway, finally provides the desert highway conservation and environment protection with some scientific guidance.
