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。

Pure-remote sensing information models are free of the numerous distributional parameters that are difficult to obtain in vast area. The following sections are included in the study.(1) The VCI and SVI based on time-series NDVI data are used to analyse regional drought and the following results were reached: As the vegetation growth status index, the response of VCI and SVI to precipitation was land cover type, temporal and site specified. So VCI and SVI have little information about drought when used to monitor regional drought especially in China that has a mountainous topographty.(2) Based on the interpretation of NDVI-Ts space, NDVI and land surface temperature was combined to construct NVDI-Ts space from which the TVDI (Temperature Vegetation Dryness Index) was obtained with line ratio method and normalized slopes method. When compared with the topsoil moisture measured in situ, TVDI are competent in regional drought monitoring. Illumed by the NDVI-Ts space, we combined the NDVI with day/night land surface temperature difference and apparent thermal inertia to construct NDVI-ΔT and NDVI-ATI spaces from which the DVDI and AVDI were estimated respectively with 8-day composite MODIS 〓 product and 16-day composite MODIS NDVI product.
具体包括以下几方面的内容:(1)VCI和SVI在干旱监测中的作用评价:探讨利用NDVI时间系列数据建立的植被状态指数和标准植被指数评价区域干旱的可行性,研究结果表明:VCI和SVI作为植被相对生长状况指标,对降水的响应随着植被覆盖类型、时间和空间等而表现出不同的敏感性,因此在大区域干旱监测中,特别是我国这样地形复杂多样的国家,VCI和SVI在干旱监测中的作用都是有限的;(2)利用TVDI评价全国干旱等级分布:结合陆地表面温度和植被指数建立NDVI-T〓空间,在NDVI-T〓空间物理意义理解的基础上,分别采用线段比值法和斜率归一化法构建温度植被干旱指数,并利用TVDI研究了我国2000年3~5月份各旬的干旱分布,取得比较满意的结果。

Soil sampling is carried on on the typical slopes, and the mountain slope location that is being researched is divided into three parts: upper slope, middle slope, lower slope, and three land use ways are selected respectively in each slope location(altitude, slope gradient and aspect are same on the whole): farm land,, reforested land, waste land are taken as sampling sites.
土壤采样选取典型坡面进行,把研究的山体坡位分为3个部分:上坡位、中坡位、下坡位,在每个坡位(海拔高度、坡度及坡向基本一致)分别选取3种土地利用方式:坡耕地、人工林、荒草地作为采样点。
