The main environment geological question is: The earth"s crust where the faultage and earthquake are active is unstable; collapse , landslide, mud-rock flow and soil erosion ; The underground karst subsides, seepage question; Basic rock expand, expend and compress soil body, the salt deposit corrode out of shape and groundwater"s corrodent harm; The soft soil question of basin; The soft rock body, cracked rock and the weathering rock are relatively poor stability; High and cold regional highways and railways" frozen soils freeze and melt calamity problem; The around rock of tunnel are unstable because of the coal seam gas, spring water, underground developed area; Project cutting slopes, constructed abandon soil and reservoir, lake"s ecology geological environmental protection issue; Thedangerous shoal of the channel % submerged reef question; The problem of rebuilding channel project and dock etc.; And the problem of unstable ground and groundwater corrosivity during building airport; At the same time, with the international big pathways" implementation and completions of constructions, adjusting the cities and counties" constructions , the crowd occupy changing , the cultivated land distribute changing and the adjustments of structure, will cause local environmental geological issues outstanding; According to multiple statistical analysis , value calculate and integrated appraise result, in the northwest and southwest of Yunnan, the traffic relatively low density, traffic engineering is relatively weak impact on environment, It is the area where a environme
主要的环境地质问题是:活动性断裂、地震带的地壳不稳定;崩塌、滑坡、泥石流及水土流失;地下岩溶塌陷、渗漏问题;基础岩体膨胀、胀缩土体、含盐层侵蚀变形和地下水的腐蚀危害;盆地软土问题;软弱岩体、碎裂、风化岩体稳定性较差;高寒地带公路、铁路建设的冻土冻融灾害问题;煤层瓦斯、涌水、地下采空区等隧道围岩不稳定问题;工程切坡、施工弃土及水库、湖泊生态地质环境保护问题;航道险滩、暗礁问题;渠化工程、码头等库岸再造问题;以及机场建设中的不稳定地基及地下水腐蚀性问题;同时,随着大通道建设的实施和完成,城镇建设的调整、人群居落的变化和耕地分布及结构的调整组合,都可能造成局部环境地质问题的突出等等。经多元统计分析数值计算、综合评价结果,滇西北、滇西南地区交通密度较低,交通工程对环境的影响程度较弱,是环境地质状况好的区域;有主要高原湖泊分布区的,包括昆明、个旧、文山的滇东南区域,环境地质状况较好;大姚、楚雄、篙明及会泽、昭通一镇雄的区域,即滇中北部中生界红层和滇东北岩溶区,环境地质状况中等;而包括保山、德宏、大理、临沧的滇西地区及景东一墨江以东、双柏一石屏一河口以西及东川一寻甸一曲靖地段的滇中一滇东地区,环境地质状况较差。云南国际大通道建设涉及全省区域,如何利用地质环境、实现可持续发展,就必须依赖于国际大通道建设与地质环境之间良性关系的建立。应本着对区域地质环境客观存在的科学认识原则、建设过程中环境效益优先的可持续发展原则、法制性原则、对大通道建设中环境地质的因地制宜及其可防治性原则。并且从组织管理、不同类型大通道、不同环境地质问题类型等方面,提出了对策措施。最后,提出了建立国际大通道建设与环境地质良性关系的宏观建议。

Urban lake landscape is one of the most active areas of the city. Human activity and natural process both impact on the urban lake landscape. Urban lake contains abundant landscape resource and social civilization. Since 1990, reconstruction and renewal of urban lake landscape has been the highlight of city construction with the development of social economy. But many improper designs destroy the natural environment of urban lake, dissever urban historical context, and bring new problems to social economy. This paper emphasizes studying on how to inherit and follow historic context and civil environment by reconstructing and renewing urban lake landscape, combined with current era features to meet the needs of urban sustainable development.
城市湖泊景区是城市中最具有活力的地区之一,是人类活动与自然过程共同作用最为强烈的地带之一,城市湖泊蕴涵着丰富的景观资源,凝聚着丰厚的地域人文精神。1990年以来,随着社会经济的发展,城市湖泊景观建设成为城市建设热点,但很多不当的设计不但给城市湖泊的自然生态环境造成很大破坏,割裂地域历史文脉,而且带来了新的社会经济问题。

In this paper,dynamic changes of lacustrine water in the Sihu area were analyzed by using remote sensing.
采用遥感方法分析了四湖地区的湖泊水域的动态变化,分析结果表明:该地区 50年代至 80年代初由于大规模围湖造田,致使湖泊水域萎缩相当严重,80年代以后,湖泊水面急剧减少的趋势得到遏制,而 90年代以后,湖泊水面基本处于无显著变化状态。

Influenced by tectonic movement, there were no sediments in the area from Oligocene to Miocene. Appearance of marlite in the Pliocene, especially in Yaqueling region, proved localized depositing environment forming, for which there had only few amount of terrigenous matters to supply. Sedimentary facies association of alluvial fan, fan delta and inland lake appeared at the early and middle stage of lower Pleistocene, and association of fan delta and inland lake appeared at the later stage of lower Pleistocene and the early stage of middle Pleistocene. Net-veined laterite appeared at the top of lacustrine deposit, which reflected pedogenesis taking place after the end of deposition. Such evolution history proves that there had no lager river system traversing this area before the early stage of middle Pleistocene.
对于江汉盆地西缘宜昌地区来说,其沉积及古地理演化表现为:早白垩世为受天阳坪断裂控制的内陆湖泊沉积环境,沉积中心在天阳坪断裂的北侧,此时几乎不存在来自黄陵地区的水系;晚白垩世同样为受断裂控制的内陆湖盆环境,但湖盆面积扩大、断裂活动减弱,且后期出现成化湖相沉积;第三纪早期盆地由断陷盆地转变为坳陷盆地,同时石膏的出现代表了局限咸化湖盆的存在;渐新世—中新世,受构造影响,缺失该时期的沉积;上新世时在鸦鹊岭一带出现的泥灰岩沉积反映了陆源物质供应不足的局限沉积环境的存在;早更新世早中期为冲积扇—扇三角洲—内陆湖泊沉积,早更新世晚期—中更新世早期为扇三角洲—湖相沉积,后期出现沉积结束以后的网纹红土化作用。
