Abstract:
绿洲土壤特性的空间变异性是土壤的重要属性之一。不同尺度上的土壤空间变异性的定量化研究可以使人们了解植物与土壤的关系,养分和水分对植物的影响以及植物的空间格局等具有重要的参考价值。本文运用GIS技术,采用传统统计学和地统计学相结合的方法,分析渭–库绿洲土壤含盐量的时空变异情况,及其揭示其绿洲土壤盐分的时空变异规律。结果表明,各时期表层土壤盐分拟合的理论模型都符合球状模型;研究区盐渍化土壤主要集中于研究区的东部和东南部,该区域土壤含盐量相当高,形成了区域积盐中心;研究区西部和西北部含盐量较低;土壤含盐量大体上有从研究区的西北、西边区域向研究区东南和东部区域的方向增加的趋势。渭–库绿洲气候与土壤条件非常适宜种植棉花,是新疆的主要棉花生产区域之一。这对研究区土地的合理利用、了解土壤的结构和功能、合理的水资源灌溉利用、土壤盐碱化防治、棉田的优化布局和棉花产业的可持续发展提供科学依据,从而对保护渭–库绿洲生态环境的稳定性做出贡献。
Spatial variation of soil properties is one of the important properties of oasis soils. Quantitative research on spatial variation of soils on different scales could help people learn the soil-plant re-lationships and the effects of soil moisture and nutrients on plant growth, and spatial patterns of plant community. In this paper, we used GIS technology combined with traditional statistics and geostatistics to analyze Spatial and temporal characteristics of soil salinity in ?gan-Kuqa Oasis. Results showed that, the theoretical model of the surface soil salt fitting the spherical model; soil salinization in the study area is mainly concentrated in the east and southeast of this area with quite high salinity, formed a regional center of salt deposition; in western and northwestern area, low salt content were observed. The oasis climate is very suitable for cotton plantation, and thus this area is one of the main cotton production bases of Xinjiang. Results from this research should provide a scientific basis for rational use of the soils, understanding the structure and function of soil, reasonable irrigation water resources utilization, soil salinity control, optimize the layout of cotton fields, and provide a scientific basis for the sustainable development of cotton industry, thus to protect the stability of oasis ecological environment.

Abstract: A total of 62 green alga strains were isolated from the soils of Nanshan Mountain, Xinjiang. Used the blot method to characterize these metal resistance, the results indicated that XJU-3、XJU-28 and XJU-36 have resistance to 0. 1 mmol · L~(-1) Co~(2+) ;XJU-28 has resistance to 1 mmol·L~(-1) Zn~(2+) and Fe~(3+) , XJU-36 has resistance to 0. 05 mmol·L~(-1) Cu~(2+). Taxonomic evalua-tion of the three strains were investigated based on the morphology and the internal transcribed spacer (ITS) regions (including the 5. 8S). Based on morphological characteristics, the three strains were likely to Chlamydomonas. Phylogenetic reconstruction with the Neighbor-joining (NJ) method using sequences of ITS(including the 5. 8S) indicated that XJU-3 and XJU-28 are closed to Chlamydomonas zebra. XJU-36 is closed to Chlamydornonas petasua.

Abstract: [目的] 本文旨在提出更有效的时间序列组合预测模型的构建方法,建立预测精度较高的时间序列组合预测模型。[方法] 以1978-2013年新疆农业机械总动力为数据源,建立了源序列的曲线回归、自回归积分滑动平均、3次指数平滑和灰色模型,并构建了预测对象和预测模型的关系数据库。提出了基于百分误差的计算属性重要度方法,依据该方法计算单一模型在组合模型中的权重,构建了单一模型预测值及其权重为输入的组合预测模型,使输出结果中完整的涵盖了时间序列不同单一预测模型的输出值特征。以误差分布特征为指标,对组合预测模型和各单一模型的预测性能进行分析。以组合预测模型拟合优度和预测值平均绝对百分误差(MAPE)作为评价指标,对基于百分误差、粗糙集、Shapley和熵权法的组合预测模型构建方法进行定量分析。[结果] 预测周期内提出的组合预测模型的最大及平均误差与各单一模型最优值相比,分别降低了27.35和6.43,误差平方和(SSE)减少了73%,平均绝对百分误差降低了1.56%。基于百分误差的组合预测模型的拟合优度与基于粗糙集、Shapley和熵权法的组合预测模型拟合优度相比,分别提高了2.40%、5.10%和2.27%,粗糙集、Shapley和熵权法的预测值的平均绝对百分误差分别为1.6730、3.7261和2.7024,而本文提出的模型的平均绝对百分误差为1.2984。[结论] 基于百分误差的组合预测模型在农业机械总动力和类似时间序列预测分析中,降低预测误差波动幅度及提高预测精度方面与其他单一模型和组合模型相比具有显著优势。
[Objectives] The combination model have emerged as a possible solution to the challenges associated with time series forecasting. In order to test this hypothesis,advantages and disadvantages of different methods used for combination model development were discussed in the present study. The models were assessed on the basis of prediction accuracy so that more effective approach for combination model for prediction is provided. Keeping in view the assessments,the prediction model for time series with higher accuracy was established.[Methods] The performance of combination prediction model was related with accuracy and weights of single model. According to their prediction accuracy on statistical data from 1978 to 2013 of total power used by agricultural machinery in Xinjiang,the cubic curve model,autoregressive integrated moving average model,cubic exponential smoothing model and grey model were used as member of combination model. Later the results of prediction models were used to develop a relational data model. On the basis of fitting error of every single model on prediction total power data,a new method of computing for importance degree of single model was developed by using the percentage error of each model,then a practicable way for calculating single model’s weight was developed by using the importance degree of each model. In the light of that method,percentage error based combination prediction model was used to predict time series data,i.e. the agricultural machinery total power of Xinjiang was fitted on percentage error based combination model. The accuracy of the proposed combination model and every single model was evaluated on the basis of minimum error,maximum error,average error,sum of the squared errors (SSE),mean absolute percent error (MAPE) and goodness of fit. Various combination prediction models on time series especially on the total power were already developed by

Abstract: 以《乌鲁木齐园林树种分类检索表》的编制为例,探讨了传统植物检索表在应用中存在的检索障碍。通过实地调查、文献查阅,并根据多年的教学、科研实践中野外采集、分类、鉴定所积累的第一手资料,采用二歧法和多歧法相结合,不按分类系统直接划分的方法编制了《乌鲁木齐园林树种分类检索表》,对传统的按分类系统,且只用二歧分类法编制检索表的格式进行了改良。该方法的主要优点①对于某一区域植物的检索鉴定,不受分类系统位置和分类单位等级的限制,便于使用;②二歧法与多歧法相结合,更便于检索表的编制和应用,编排的种类过多时篇幅相对少,降低因植物种类多而产生的编排难度;③检索表选用简便通俗而稳定的性状特征,在整个生长季节对各种树木的鉴定几乎都不会出现因缺乏树种观察器官而产生的检索障碍。本检索表将会给该地区大中专院校的教学、科研和园林工作带来极大的方便。

Abstract: 选择新疆阿克苏市柯柯牙典型的5种果树:红枣(Ziziphus jujuba)、核桃(Juglans regia)、苹果(Malus pumila)、葡萄(Vitis vinifera)和香梨(Pyrus sinkiangensis),并对树种叶面滞尘量及其对水分利用效率的影响进行研究。结果表明,5种果树滞尘能力为葡萄5.37 mg/cm2>香梨4.55 mg/cm2>红枣3.88 mg/cm2>核桃3.03 mg/cm2>苹果0.92 mg/cm2。水分利用效率为葡萄(2.646 μmol?mmol-1)>香梨(1.810 μmol?mmol-1)>核桃(1.698 μmol?mmol-1)>红枣(1.359 μmol?mmol-1)>苹果(1.043 μmol?mmol-1)。通过分别比较5种果树滞尘量与水分利用效率之间的相关性得出,5种果树的滞尘量与净光合速率、蒸腾速率、水分利用效率之间并无显著相关关系。表明果树在长期适应极端环境的过程中,形成了自身的调节机制,滞尘量对果树的水分利用效率的影响不大。
Five typical fruit trees cultivated in Kokyar of Aksu,Xinjiang were selected to study the dust-retaining capability and water use efficientcy.The dust retaining capacity of the five fruit trees was in the order of Vitis vinifera>Pyrus sinkiangensis>Ziziphus jujuba>Juglans regia >Malus pumila.The order of water use efficiency was V.vinifera >P.sinkiangensis>J.regia>Z.jujuba >M.pumila.No significant correlations were found between dust retaining capacity and photosynthesis,transpiration and water use efficiency,suggesting that fruit trees had formed their own regulatory mechanisms in the long process of adaptation to extreme environments.Dust on fruit tree leaves did not have strong effect on water use efficiency
