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。

The forecasted total wastewater volume in 2020 is 28 104 m3/d . It is put forward that a classification treatment mode is used to realize integration of centralized and decentralized treatment. The construction of four centralized wastewater treatment plants named Baozhen, Xinhe, Chengqiao and Changxing is proposed. For the wastewater from other towns and centralized residential areas, the small decentralized ecological treatment modes such as constructed wetlands are used. The courtyard treatment mode is used for the wastewater from the rural arear.

预测三岛地区至2020年的污水总量约为为28 104m3/d ；提出采用&分级治理&的模式，以真正实现污水集中与分散处理相结合的方式；建议崇明三岛建设堡镇、新河、城桥、长兴等4座集中式污水处理厂，其余城镇和集中居住区的污水采用人工湿地等小型生态化治理方式分散处理，广大农村地区的污水则推广庭院式治理方式。

In addition,α-alkenoyl ketene--acetals mainly used as the synthons of 3C and 5C, theα-functionalized reactions of which just limited on some simple reactions, as bromination, nitration, acetylation. However, the understanding of the forming of C-C bond atα-position is far from enough.

另外，对于α-烯酰基二硫缩烯酮的研究则主要集中在其作为3C或5C合成子的研究上，其α-位的官能化研究只是停留在溴化、硝化、脱羧等简单的反应之上，而对α-位C-C键的形成还缺乏足够的认识。

1引言由于采用热水供热系统具有采暖质量好、节能、运行安全、设备维护费用低等优点，热水供热系统目前已经成为我国北方城镇集中供热的主体形式，同时也推动着热水锅炉技术的发展和进步，使其朝着大型化和多型化方向发展〔1，2〕。由于我国环境保护标准的限制并考虑到燃烧设备的运行可靠性，目前，我国绝大多数集中供热用热水锅炉是大型链条炉排热水锅炉。
