In this paper, as a case of Karamay, we have studied on space-time changement of soil quality in oasis of arid area. We measured quality for different land use types and years in same type by combinativing field sampling for Karamay in Xinjiang and analysis in laboratory, which is directed by former theory of soil quality. Then we did integrated evaluation of soil quality for different land use types, and had drew some conclusions as followed: In four land use types, the soil bulk density of layers(0～15cm) for farmland and tree land is bigger than the other land use types.The organic matter of every layer in manpower Tamarix Bulrush land is bigger; organic matter of Tamarix Bulrush land release efficiency nitrogen which result ration of C/N is higher; total nitrogen of all layers in farmland variety great as being effected by mass use of nitrogen in agriculture; deadwood and defoliation of tree、shrub and bulrush pooled in 5cm layer to result that quick nitrogen is the biggest among all layers. The total salt of nature shrub tree land for every layer being bigger than farmland explain that nature shrub thee land strongly stand salt and farmland for basification in this area; that the nutrient of face layer is bigger than the ground layer may be explained by that vegetation gather nutrient to be stored in deadwood and defoliation.

本文对以克拉玛依为例，对干旱区绿洲土壤质量的时间空间变化进行研究，在有关土壤质量的研究理论指导下，通过田间调查取样和室内分析相结合的方法，对新疆克拉玛依市农业开发区的不同土地利用方式及同一土地利用方式下不同利用年限土样土壤理化性质进行测定，从而对新垦绿洲不同土地利用类型土壤质量进行综合评价，结果如下：四种土地利用方式中，农地、乔木林地表层(0-15cm)土壤容重较大；各土层人工柽柳芦苇地的土壤有机质含量均较大；柽柳芦苇地的有机质在矿化过程中所释放出有效氮，导致柽柳芦苇地的C/N比例较高；受到农业耕作使用大量氮肥的影响，农地各土层全氮含量变异较明显；乔木、灌木及芦苇的枯枝落叶主要集中在5cm范围之内，导致几种土地利用方式类型下该层土壤速效氮最大；天然灌木林地的土壤总盐在各层均较大，其次是农地，说明天然灌木林地的高耐盐能力，以及该区农业生产用地的土壤盐碱化程度较重。

Have successfully taken part in organized many large-scale performances, such as "century bell sounded to welcome the dawn of the century" series of seven nights, 315 large-scale variety show "clearly my heart," Chongqing "Love of the Three Gorges - Chang Hui-mei's concert "," Night of Fengyuan Pharmaceutical Health - 2001 Lau Anhui World Tour Concert "," Song of volunteer awards show "," sharing a bright - Clayderman Classical Piano Recital,"" China International Table Tennis Challenge Cup "," mine-laying - Dennis large Dream Magic,"" Longjin National Chung - Shanghai Ballet White-Haired Girl "p" 2003 Strawberry Festival changfeng listed large-scale gala day "p" 2004 World Masters Violin silent Stiga China tour,"" Pinocchio 2005 hundred games tour Eastern Region "and other activities, have achieved great success and well received by the audience, but also in co-operation provides a good publicity platform.

曾成功参与组织举办过很多大型演出活动，如《敲响世纪之钟，迎接世纪曙光》七场系列晚会，大型315综艺晚会《明明白白我的心》，重庆《情系三峡--张惠妹演唱会》、《丰原药业健康之夜--2001刘德华世界巡回安徽演唱会》、《志愿者之歌颁奖晚会》、《共享光明-克莱德曼经典钢琴演奏会》、《中国国际乒乓球擂台赛》、《布雷-丹尼斯大型梦幻魔术》、《龙津国庆颂--上海芭蕾舞团白毛女》﹑《2003长丰草莓节上市日大型文艺晚会》﹑《2004世界小提琴大师斯帝默中国巡演》、《2005木偶奇遇记华东区百场巡演》等活动，都取得了巨大成功，广受观众欢迎，也为合作单位提供了良好宣传平台。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
