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。

Beijing is provided with typical urban landscape, forest land is the maximal and basal landscape patch type (area proportion 42.534%), glebe field (28.754%),spinney land and urban (26.912%) and town residential landuse (10.344%) are main landscape patch categories in Beijing. From landscape, landscape patch types and landscape patch categories levels, landscape patch distributing centralize, and patch shape is simple, main landscape patch fractal dimension indexes are under 1.1, so urban landscape pattern is high influenced by human disturbance.2. From 1985 to 2007, Beijing landscape pattern variational characteristics are as follows:(1) During 1985-2007, patch types and categories change is little, but area and patch number of patch types and categories change distinctly. Town residential landuse area increased 7.66% of Beijing total area, farmland and forest land area decrease in the mass. The total patch number increased at first then decreased. taking one with another, the total number is decreasing, and patch number of farmland and forest land are most distinct.

本研究的主要研究结果如下：1、北京市具有典型的城市景观特征，林地用地的面积占市域面积的42.534%，为基质景观斑块类型，旱田(28.754%)、灌木林(26.912%)、城镇用地(10.344%)是北京市主要景观斑块种类；从景观、景观斑块类型以及景观斑块三个层次的研究均表现出北京市各景观斑块类型及景观斑块集中分布的现象十分突出，斑块形状简单，主要景观斑块种类的景观分维度指数值均不足1.1，表明城市景观格局受到了较大的人为影响。2、北京市1985-2007年间城市景观格局的主要变化特征表现为以下几个方面：(1)在研究时段内，北京市景观斑块种类变化不大，景观组分面积和斑块数变化明显，其中最为显著的是北京市城镇建设用地面积呈单纯的增加趋势，增加幅度为北京市总面积的7.66%，农业用地与林地的面积虽呈波动变化但总体呈减少趋势；景观斑块数量先增后降，总体呈下降趋势，其中耕地与林地斑块数的变化最为明显。

Secondly,The dairy district had better build a special forage production base.Thirdly,The type of pasture is annual cultivated grassland. Applying this systerm to the stable forage production base, the expendiute on green forages can be redunced by 10% in comparition wihe applying the other systerm.

结果表明：(1)不同用地类型的饲草基地，其最优的青饲料供应体系是不同的；(2)为降低奶牛小区青饲料供应成本，改善其青饲料结构，奶牛小区应建立专业的饲草基地；(3)对利用退耕地建立饲草基地的奶牛小区，其优先选用的青饲料供应体系的特点是：应用该体系建立的饲草基地，其建植的草地只存续一年。

I've written before that approximately 2/3 of the earth's tillable soil is completely devoid of Selenium, a vital trace element and power mineral required not only for the production of SOD but also one that is a powerful immune booster, cancer fighter and longevity mineral too, that most people have virtually no selenium in their diet which is another great reason to make sure that you're taking the true RDA of 200mcg per day.

我写此之前，大约有2 / 3地球的耕地土壤是完全缺乏硒，一个重要的微量元素和矿物质的权力，不仅需要为生产的SOD ，而且还一说是一个功能强大的免疫强心针，癌症战斗机和长寿的矿产太，大部分人都几乎没有硒在他们的饮食，这是另一个重要原因，以确保您以真正的推荐的每天
