基于遗传算法的反倾层状岩质边坡极限分析上限解

倾倒破坏是反倾层状边坡主要的失稳类型之一,而当反倾层状边坡内存在软弱夹层、外倾结构面等因素时,传统的纯剪断或纯折断破坏将不再适用,如何有效地建立一种该类型边坡的稳定性分析方法对边坡工程设计显得尤为重要。在此基础上,本文针对反倾层状岩质边坡平动-转动组合破坏问题,利用塑性极限分析上限定理,结合相关联流动法则和变形协调条件建立容许运动场,构建考虑平动加转动的岩质边坡稳定性极限分析理论计算模型,进一步采用遗传优化算法进行全局极值搜索,得到基于遗传算法的平动加转动岩质边坡极限分析稳定性系数上限解和相应的最优折断面。采用该方法与改进的 Goodman Bray方法进行对比,计算结果表明所提方法具有一定的适用性。同时利用该方法,对反倾岩质边坡的稳定性影响因素进行了敏感性分析。     

近20a西喀喇昆仑地区吉尔吉特河流域冰川面积变化及其对气候变化的响应

冰川被誉为“固态水库”,对区域生态环境和发展至关重要。喀喇昆仑山地区的冰川出现了退缩停滞乃至前进的现象,被称为“喀喇昆仑异常”。为探明西喀喇昆仑地区吉尔吉特河(Gilgit River)流域的冰川面积变化及其影响因素,本文基于1993、2000、2016年三个时期的多景LandsatTM/ETM+/OLI遥感数据,通过目视解译法提取三期冰川边界。结果表明:(1)1993—2016年,吉尔吉特河流域冰川面积共萎缩了45.82±9.07km^2,约占1993年冰川总面积的4.07±0.80%。其中,1993—2000年冰川面积的年均萎缩率为0.19±0.02%,2000—2016年冰川面积的年均萎缩率为0.17±0.03%,即近15a来研究区冰川面积萎缩呈微弱的减缓趋势。(2)1993—2016年研究区内共有12条冰川发生过前进现象,其中G073768E36822N(冰川编码)冰川发生了较为快速的前进,在1996—1999年末端前进了477m,前进速率为159m·a^-1。(3)近40a来,吉尔吉特河流域的气温呈持续上升趋势,降水呈先减少后增加趋势。气温升高是研究区冰川退缩的主要原因,降水的增加缓解了因升温而导致的冰川面积萎缩。     

不同苔藓斑块对亚高山针叶林土壤呼吸和有机碳累积的影响

苔藓植物作为森林生态系统最常见的地被植物之一,对生态过程起着重要调控作用。为探明不同苔藓植物对亚高山生态系统碳循环过程的影响,本文以封闭式动态气室法,对川西贡嘎山东坡峨眉冷杉生态系统赤茎藓(Pleuroziu schreberi)和星塔藓(Hylocomiastrum pyrenaicum)两种苔藓斑块土壤以及裸地斑块土壤CO_2排放速率进行了定位观测,同时探讨了不同苔藓斑块对土壤有机碳累积的影响及潜在途径。结果显示:(1)苔藓植物显著改变了亚高山针叶林土壤CO_2排放速率及其季节变化特征,但不同苔藓植物的影响程度具有差异:赤茎藓和星塔藓作用下土壤CO_2排放速率分别增加了28.5%和46.8%,星塔藓与赤茎藓相比其对土壤CO_2排放的促进作用更显著;(2)苔藓斑块对土壤有机碳(SOC)和溶解性有机碳(DOC)的影响具有物种特异性,两种苔藓中,赤茎藓能够显著促进SOC和DOC累积,但星塔藓的影响不显著。该结果反映了亚高山生态系统不同苔藓物种在促进生态系统碳循环方面的生态功能的差异,由此,在开展亚高山生态系统碳循环以及土壤有机碳储量研究时,应充分考虑苔藓物种对土壤碳过程/碳平衡的作用机制和生态功能差别。     

基于地理加权回归模型的典型山地卫星反演降水产品降尺度研究

降水是陆地水循环的关键变量,高分辨率降水数据的获取是准确模拟陆地水循环过程的前提。虽然卫星反演降水产品具有较强的空间代表性和连续性,但其空间分辨率较低的问题限制了它的应用。以太行山、横断山和喀斯特山区为研究对象,基于降水与高程(DEM)、植被指数(NDVI)之间存在较好相关关系的假设,构建了GPM降水(Global Precipitation Measurement Mission)与高程、植被指数的地理加权回归模型,得到了2014—2016年研究区1km分辨率GPM降水数据。研究结果表明:地理加权回归模型能有效地提高GPM数据的空间分辨率。降尺度后,GPM数据精度在太行山和横断山区略有提高。年尺度上,相比于原始GPM数据,太行山和横断山区降尺度数据站点实测数据的确定系数分别提高了0.06和0.08,RMSE分别降低了0.45%和3.89%,MAE分别降低了0.16%和1.70%;月尺度上,太行山区67%的月份,横断山区83%的月份GPM产品降尺度后更加接近于站点实测数据。喀斯特地区GPM数据降尺度后精度略有下降,降尺度后,年尺度的降雨数据与实测数据的RMSE和MAE分别增加了10.00%和8.00%,R^2降低了0.06,月尺度上仅8月和9月降尺度后的精度更高。降雨与地形和NDVI的关系较弱是喀斯特地区降尺度效果较差的主要原因。
