为研究栅栏防沙的动力学机制,运用风洞中PIV所测风速资料,从空气动力学角度对直立栅栏的最佳疏透度范围进行了讨论与评价。结果表明,不同研究者所得栅栏的最佳疏透度范围不尽相同,大致范围在0.2~0.6之间,结果非常分散。PIV资料评价的栅栏最佳疏透度在0.2~0.3之间,该疏透度范围的栅栏周围气流湍流度较低,对风能的耗散较大,能有效抑制过境风沙流,理论上属于防沙的最佳疏透度,但实践操作中为了降低成本,
This paper explores the potential to improve the impervious surface estimation accuracy using a multi-stage approach on the basis of vegetation-impervious surface-soil (V-I-S) model. In the first stag
目前在大学里面为职教师资专业设置的课程体系仍然是传统的学科系统化模式。本文提出在职教师资培养中采用基于工作过程系统化的学习领域课程体系。学习领域课程模式的主导思想将以往学科系统化课程模式用工作过程系统化代替。将每门课程通过工作过程分析最后分解为若干个学习情景,这种课程设置模式是目前职教师资培养应该重点推广的模式。

城市供、排水管网科学化管理是实现城市安全、经济供水以及污水处理的可靠保证。目前我国绝大部分城市供、排水管网管理方法和技术较为落后,基本上还是采用人工方式管理和基于经验的决策,存在与其他市政设施管理信息集成化差,造成数据冲突延误等问题。针对这一现象,提出了基于GIS的城市供、排水管网与其他市政设施管理信息集成系统的理论、技术和方法,以使供、排水管网的信息化管理系统更快、更好的发展。
在3S技术的支持下,以奈曼旗1975年、1985年、1995年和2005年的遥感影像为信息源,分析了研究区近30 a人工造林对沙漠化过程的影响。结果表明,在持续的人工造林过程影响下,沙地面积呈现出持续减少的趋势,其中固定沙丘面积减少幅度尤为显著,面积净减量为39 545.77 hm2;沙漠化程度指数呈现出线性减少的变化趋势,自1985年以来,减少幅度尤为明显,由1985年的0.21下降到2005年
