利用探索性空间分析方法（ESDA）和迪氏分解模型（LMDI）研究长江经济带2002~2013年工业废水排放的时空格局演化和主要驱动因素。① 时空格局演化方面,时间上工业废水排放先上升后下降,在2005年达到峰值。空间上,排放量自上游向下游增加;高排放城市减少,中排放城市增多;工业废水排放自下游向中上游转移,并由大城市向中小城市扩散;呈现明显的空间集聚状态。② 驱动因素方面,经济发展效应和技术进步效应分别是工业废水排放增多和降低的主导因素;产业结构效应的影响取决于产业发展政策的调整;人口规模效应影响较小。  相似文献

2010年秋至2011年春,泰安市长时间无有效降水,遭遇了秋冬春三连旱,气象干旱达百年一遇。为此,泰安市政府组织全市国土资源系统和驻泰地勘单位开展抗旱找水定井打井工作,笔者所在单位被指定为泰安市抗旱找水定井单位。根据此次找水定井实践,结合泰安市区域水文地质条件,提出了泰安市山丘区地下水找水方向,供同行在泰安市山丘区找水定井时参考。  相似文献

泰安市岩溶塌陷集中分布在泰山火车站南侧以旧镇铁路三角区为中心的城区岩溶水源地、牟汶河畔的旧县岩溶水源地、东西羊娄村3个塌陷分布区。岩溶塌陷经历了发生→发展→高峰→衰减的历程。该文概述了泰安市岩溶塌陷发育历史与现状及其危害,形成的地质环境背景,阐述了岩溶塌陷与岩土体类型、地质构造、大气降水、人类对岩溶地下水开采活动等影响因素的关系。  相似文献

Spatial characteristics and driving forces of the morphological evolution of East Lake,Wuhan

The shapes of the urban lakes in Wuhan city have been strongly influenced by the rapid industrialization and urbanization experienced in recent decades.Based on topographic maps and remote sensing images,the temporal and spatial changes of East Lake,Wuhan city,over the past two decades were analyzed.The landscape shape index(LSI)and centroid method were applied to analyze the evolution of lake morphology and its causes.Several key results were obtained.(1)The surface area of East Lake decreased sharply by 2.13 km2 from 1995 to 2005,and slightly by 1.00 km2 from 2005 to 2015.The shoreline length of East Lake displayed a continuous trend of decline during the study period:The length reduced by 21.89 km from 1995 to 2005,and by 0.67 km from 2005 to 2015.The LSI values,7.04(1995),6.46(2005),and 6.28(2015),displayed an accelerated downward trend,indicating a reduction of complexity in East Lake and the intensification of manual interventions in the water body.(2)The changes to East Lake displayed a clear temporal and spatial heterogeneity.The centroid of East Lake moved northeast from 1995 to 2005 and southeast from 2005 to 2015.(3)The reduction in the area of East Lake was mainly affected by human activities.A lake area of about 4.8 km2 was converted to other land uses during 1995-2005,most of which was unused land,whereas from 2005 to 2015,0.43 km2 of the lake area was converted into built-up land,and 0.25 km2 was converted into other land uses.The reduction in area was caused by infrastructure construction by the government,the development of the real estate industry,illegal construction by villagers,and the development of scenic spots for tourism.The driving forces of this reduction included Wuhan's growing population,and the rapid development of the economy and urbanization between 1995 and 2015,which has resulted in a large demand for land.Finally,a formation mechanism model was constructed by analyzing the causes of East Lake's morphological evolution.  相似文献
