Study on NHX1 Gene Functional Comparisons between Chenopodium glaucum and Oriza sativa Using Affymetrix Gene Chips in Transgenic Arabidopsis GUO Ji-na;ZHANG Fu-chun 2010, 47(1): 1-6.  Abstract ( )   [Objective and Method]The gene chip is a DNA analysis technology of high throughput and high efficiency which has been widely used in analysis of resistant function.In this study, using Affymetrix Arabidopsis whole-genome expression gene chip, the differential expression analysis of gene was carried out with the transgenic A. thaliana .[Result]In the transgenic Arabidopsis tissues under salt stress, 394 co-expression genes were selected from the four groups, they accounted for 1.64; of the total number of genes, in which there were 177 up-regulated expression genes and 217 down-regulated expression genes. These genes were initially divided into 12 gene categories, including response to abiotic or biotic stimuli, response to stress , electron transport or energy pathways, signal transduction and transcription, and so on. Our results show that the process of plant salt-tolerant is a multi-gene changed complex process that involves many changes of variety related genes.[Conclusion]The results of comparison scatters and cluster analysis illuminate that the salt tolerance of transgenic Arabidopsis cgNHX1, cgNHX1dc, osNHX1 and osNHX1dc have successively weakened.Our study will contribute to find the differences between halophytic and glycophytic species in the mechanism of plant salt tolerance and the function analysis of hydrophilic C-terminal, provide a favorable evidence for the study of the mechanism of plant salt-tolerance between halophytic and glycophytic species, and offer new methodology in study the mechanism for salt-tolerant plants, provide a basis for practical applications of salt-tolerant mechanism in plants.

The evaluation indices system of ecological bearing capacity in Kanas Scenic Spot was established using principal components analysis (PCA) and analytic hierarchy process (AHP). On this basis, 13 indices including the resources, environment and social-economy, which were separated from the resource bearing capacity, environment bearing capacity, ecological elasticity and ecological bearing pressure, were chosen as the sustainable development degrees indices. And the whole Kanas Scenic Spot(or different period) was divided into several sustainable development degrees with different sustainability of ecosystems according to the ecological load-bearing (negative direction and positive direction) index calculated. [Result]The results showed the ecological bearing index in Kanas Scenic Spot was decreased from 0.066 9 in 1992,to 0.048 5 in 2000 and 0.004 6 in 2005.The sustainable bearing state was decreased from sustainal bearing capacity in 1992 and 2000 to the poor one in 2005.[Conclusion]Which was occurred mainly due to the increasing of tourism development, population and economical activities. Thereby,all the obtained different data provided scientific basis for the regional sustainable development.

Effects of Cotton Cropping Cotton Soil on Microorganism and Soil Enzyme Activity SHI Chong;LIANG Zhi;XU Wan-li;SHAN Hong-bin;JIA Hong-tao;WANG Li 2010, 47(1): 163-167.  Abstract ( )   [Objective and Method]The studies were carried out on the effects of 5, 10, 15 and 20 years continuous cropping cotton soil on the microbial quantities, activities and enzyme activities in Xinjiang.[Result]The results showed that continuous cotton cropping has great effect on the number of its soil microbes and soil enzyme activities. With increasing year of cropping, the amount of bacteria, actinomycetes and fungi had a slight decrease. The amount of bacteria in the soil microorganisms proves to have the absolute superiority over actinomycosis and fungi. With increasing year of cropping, the B/F had a slight decrease. [Conclusion]The soil urease, phosphatase,invertase of cotton field with different cropping years were determined.The results demonstrated that the change of urease and invertase were similar to one another,which was increased with the increasing of continuous cropping years,but the activity of phosphatase was decreased first,then was increased with the increasing of continuous cropping years.

Study on Spatial Variability of Soil Water and Salt under the Two Vegetation Coverages LI Bao-fu;XIONG Hei-gang;ZHANG Jian-bing;LONG Tao 2010, 47(1): 168-173.  Abstract ( )   [Objective and Metnod]This paper comparatively analyzes the characteristics of the spatial variability of soil profile average water and salt content in the bare land and vegetational area using the typical salinizational area of oasis-desert ecotone in Qitai as the study area.[Result]The results showed that the soil water and salt content of bare land and vegetational area obey normal distribution; soil salinity belongs to moderate variability with a stronger spatial autocorrelation. Soil moisture variability in the bare land belongs to weak variability with moderate intensity of the spatial autocorrelation; vegetational area belongs to medium (weaker) variability with strong spatial autocorrelation. Bare land correlation distance is about 1/10 of vegetational area. With soil depth increasing, the activity changes of soil salinity in bare land and vegetational area are as follows: active layer, sub-active layer and stabler layer. Soil moisture change and its relationship with salt content are inconsistent, the surface of bare land affected largely by random factors is the most active and its correlation with salinity is also poorer,while the vegetation area in the middle and lower layer (60-80 cm) is the most active, which shows highly positive correlation with the salt. [Conclusion]Affected by random factors and structural factors (such as vegetation, micro-topography, etc.), the spatial variability of soil water-salt in the two vegetational coverages shows obvious difference and reflects significant active force and reactive force that the vegetation affects the water and salt distribution and the random factors of water and salt distribution.

Research on Evaluation of Soil Fertilities of Farmland at County Level in Xinjiang based on GIS CHEN Shu-huang;GENG Qing-long;ZHANG Yun;ZHUANG Yu;DONG Ju-he;JIA Deng-quan;LAI Bo 2010, 47(1): 184-188.  Abstract ( )   [Objective and Method]Based on the geographic information system(GIS) and the second general survey soil,overlaying the current landuse map with the basic farmland protection map and the soil map,forming 7 352 patches, which are used as the basic management and evaluation cells.This research selected twelve influencing factors from three aspects such as soil nutrient content,profile situation and land management,and the evaluation system and model of farmland fertility was built up. Thegrade of arable land productivity was formed according to the theory of Fuzzy Mathematics, Telphi Principle and Analytic Hierarchy Program,and the farmland fertility of Kuche county and analysis of its spatial distribution were evaluated.[Result and Conclusion]The results suggest that 73 553.52 hm~2 farmlands could be divided into six grades,the grade one was 7 713.07 hm~2,the grade two was 20 526.13 hm~2,the grade three was 14 621.53 hm~2,the grade four was 11 987.8 hm~2,the grade five was 11 302.33 hm~2 and the grade six was 7 402.53 hm~2,the fertility of grade one to six account for 10.49;,27.91;,19.88;,16.3;,15.37;,10.06; respectively.
