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 post-operational patient on liquid or semiliquid diet injected insulin subcutaneously before three meals,applied inˉsulin according to blood sugar level until end of perioperative period.

目的 探讨糖尿病对耳鼻咽喉—头颈外科患者手术后并发症的影响以及糖尿病患者的围手术期治疗方法对51例接受耳鼻咽喉及头颈部不同类型手术的糖尿病患者，观察其围手术期并发症，并于术 3天改三餐前0.5h皮下注射速效胰岛素治疗，根据血糖的测定结果，开始剂量约为4～8U；对术后禁食需要补液的患者，按葡萄糖3～4g/胰岛素1U的比例给药，并每日监测血糖指标；术后进流质或半流质饮食的患者，于三餐前皮下注射胰岛素，按血糖测定情况给药，直至围手术期结束。

Methods 51patients with diabetes accepting various otorlaryngology-head and neck-surgical operation were adopted,regardless of previous treatments.Three days before operati on they all accepted regular insulin injecti on subcutaneously half an hour before three meals.The first dosage was roughly4～8U,then adjusted according to blood sugar levels.For the fasting patients who demanded fluid replacement post-operationalˉly,we infused solution in proportion to1U insulin/3～4g glucose and monitored everyday blood sugar in the meantime.The post-operational patient on liquid or semiliquid diet injected insulin subcutaneously before three meals,applied inˉsulin according to blood sugar level until end of perioperative period.
