Xinjiang is located in an extremely arid area in northwest China,where there are ideal places to explore the distribution patterns of species richness and their affecting factors under extreme conditions because of the complicated topographical and climatic conditions and the diversity of habitats. In this study,the relationships between the distribution patterns of species richness of vascular plants and the climatic factors in Xinjiang are analyzed based on the available data of vascular plants and climatic factors. The results reveal that the species richness increases with the increase of annual precipitation (AP) and actual evapotranspiration (AET),and the curve of species richness of vascular plants with the increase of MAT and PET is unimodal. In all the subregions,species richness increases significantly with AP. Species richness patterns with the increase of MAT are different in the mountains and basins,it increases at first and then decreases with the increase of MAT in mountains,but decreases monotonically in the basins. At different water deficit (WD) levels,the increase rate of species richness is decreased with the increase of AP at high WD. Species richness increases with the increase of MAT at low WD level but decreases at high WD level.","PeriodicalId":8385,"journal":{"name":"干旱区研究","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69830390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the satellite data and climate data,this paper analyzes the variation of two lakes in the Ulan Buh Desert. Using CBERS CCD data during the period from 2000 to 2008,the best wave bands were chosen to process the image,such as the high-accuracy geometric registration and mosaic,the brim information was extracted,and the change figures of the lakes in the Ulan Buh Desert were charted. A spectral reflection curve was charted with a TM image in 2000 to identify the changed area of the lakes. In order to avoid the contingency,the areas of each lake in recent continuous years were used to calculate the average area of each lake. The correlation coefficients between lake areas and climate change in recent 20 years were calculated. The result shows that the trend was accordant well with the result of remote sensing detection,and there was a significant positive correlation between the lake area and the annual precipitation. The lakes with small area were more sensitive to climate change than those with large area. The study result shows that remote sensing is of high usability in monitoring the lakes in desert,especially in west Inner Mongolia.","PeriodicalId":8385,"journal":{"name":"干旱区研究","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69831247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study,the species richness and structure of wild fruit forests in the Ili Valley were analyzed based on the investigated data from 67 sample plots. The results show that Juglans regia,Malus sieversii,Armeniaca vulgaris and Prunus sogdiana forests are the main wild fruit forests in the Ili Valley. In total,207 species in 141 genera and 46 families have been recorded. Species richness is higher in the A. vulgaris and P. sogdiana forests than that in the J. regia and M. sieversii forests. Stem density of the M. sieversii forests is significantly higher than that of the A. vulgaris forests. Mean stem height (Hm) of the J. regia forests is higher than that of the P. sogdiana forests. There is no significant difference in mean stem diameter at breast height (Dm) among the four forest types. Species richness tends to decrease,whereas Hm and Dm tend to increase,and there is no significant change of stem density with the increase of altitude. The results of a canonical correspondence analysis (CCA) reveal that the J. regia forests are mainly distributed in the warm areas,whereas the M. sieversii forests in the cold regions,and the A. vulgaris forests widely across the Ili Valley. Compared with other three forest types,P. sogdiana forests are only distributed in the mountainous areas in Huocheng County,where water availability is relatively high. The wild fruit forests in the Ili Valley are suffering from the severe destruction due to the intensive human activities,and they should be protected in some ways,such as the collection of germplasm resources and ex-situ conservation.","PeriodicalId":8385,"journal":{"name":"干旱区研究","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69830827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
