Abstract. Light-absorbing dissolved organic carbon (DOC) constitutes a major part of the in glacierized regions, and has important influences on cycle radiative forcing glaciers. However, few DOC data are currently available from regions Tibetan Plateau (TP). In this study, characteristics medium-sized valley glacier (Laohugou Glacier No. 12, LHG) northern TP were investigated. Generally, concentrations LHG comparable to those other around world. snow pits, surface ice (superimposed ice) 332...
Cryoconite holes, water-filled pockets containing biological and mineralogical deposits that form on glacier surfaces, play important roles in mass balance, glacial geochemistry carbon cycling. The presence of cryoconite material decreases surface albedo accelerates loss, a problem particular importance the rapidly melting Tibetan Plateau. No studies have addressed microbial community composition holes their associated ecosystem processes glaciers. To further enhance our understanding these...
The seasonal variation characteristics of the water quality Jinpen Reservoir and impacts rainfall runoff on reservoir were investigated. Water monitoring results indicated that, during stable stratification period, maximum concentrations total nitrogen, phosphorus, ammonia organic carbon, iron ion, manganese ion in at bottom September 6 reached 2.5 mg/L, 0.12 0.58 3.2 0.97 0.32 respectively. Only heavy storm can affect main cause to seriously deteriorate. During storms, was destroyed,...
Covering about 30% of the global total land area, desert ecosystems have been influenced by warming and nitrogen deposition. However, it remains unclear how respond to Therefore, we conducted a greenhouse experiment examine impacts N addition on plant–soil system Neotrinia splendens, dominant plant in ecosystem Northern China. Our findings revealed that low-N dose (N1) high-N additions (N2) increased biomass 22.83% 54.23%, respectively; meanwhile, moderate (T2) severe (T3) decreased 39.07%...
Multivariate statistical techniques, including cluster analysis (CA), principal component (PCA), factor (FA) and discriminant (DA), were used to evaluate temporal spatial variations interpret a large complex water quality data sets collected from the Songhua River Basin. The sets, which contained 14 parameters, generated during 7-year (1998-2004) monitoring program at different sites along rivers. Three significant sampling locations (less polluted sites, moderately highly sites) detected by...
Abstract Soil net nitrogen (N) mineralization is a key biogeochemical process influencing plant available N and primary productivity in terrestrial ecosystems. However, the spatial variations controlling factors of soil ( R PNM ) arid semi‐arid grasslands are less studied unclear. In this study, we investigated by performing laboratory incubation experiment. samples were collected from 30 sites three east–west transects on Inner Mongolia Plateau (MP), Loess (LP) Tibetan (TP) along 3200 km...
水鸟是湿地生态系统健康的指示生物,人类活动对其影响日益严重.研究自然保护区内的水鸟生境适宜性变化可以为湿地恢复提供帮助.通过层次分析法确定水鸟生境影响因子的权重,建立生境适宜性指数模型,根据TM遥感影像图和相关数据计算出安徽省升金湖国家级自然保护区19862011年5个年份的水鸟生境适宜指数,并结合GIS空间分析生成的水鸟生境适宜性分级图,分析升金湖建立保护区后水鸟生境适宜性变化.结果表明:升金湖地区在1986年建保护区后的几年间水鸟生境适宜性相对平稳,但是仍然有较为明显的下降;1990s后期,该地区水鸟生境适宜性开始显著恶化,一直持续到2000年之后才有小幅度的回升.水鸟生境适宜性最好的区域由片状分散逐渐转变成小范围聚集,适宜区域也在由实验区和缓冲区向核心区迁移的过程中显著缩减.本文还讨论了在研究中存在的不足,并提出一些恢复水鸟生境的建议.;Water bird is an indicator of a healthy wetland ecosystem. It has been affected more and by human activities recently....
Plant restoration strategies are ubiquitously employed for the purposes of soil and water conservation ecological improvement in forest ecosystems. Despite N temperature being acknowledged as pivotal factors affecting plant outcomes, their effects on fertility, microbial communities, shrub biomass remain underexplored, particularly loess hilly regions China. Here, we examined growth patterns nutrient acquisition abilities three species, Periploca sepium, Amorpha fruticosa, Vitex negundo,...
The Ili River Basin (IRB) is located in the northwest of China. With its large-scale zone and abundant resources, it believed to be a “wet island” biotic resource storehouse dry regions Eurasia. IRB has stable ecological conditions water providing natural for agricultural production human settlements. population increasing economic development advancing, competition land resources becoming fierce, leading some problems this region. Therefore, understanding spatiotemporal changes driving...
The terrain effect on atmospheric environment is poorly understood in particular for the polluted region with underlying complex topography. Therefore, this study targeted Sichuan Basin (SCB), a deep basin severe PM2.5 pollution enclosed by eastern Tibetan Plateau (TP), Yunnan-Guizhou Plateaus (YGP) and mountains over Southwest China, we investigated seasonal distribution meteorological mechanism based WRF-Chem simulation stuffing It characterized that three-dimensional of topography-induced...
