Statistic and econometric regression models were established in this study to analyze and predict industrial water demand,
water deficits, and their future uncertainty in Beijing—a Chinese city with a severe water stress problem. A forecasting model
was selected based on a modeling evaluation by comparing predictions with observations. Four scenarios were designed to simulate
and analyze the future uncertainty of industrial water demand and the water deficit of Beijing. The modeling results for industrial
water demand suggested that Beijing industry would face a water deficit between 3.06 × 108 m3 in 2008 and 2.77×108 m3 in 2015, though its industrial water demand would decrease from 6.31×108 m3 to 4.84 ×108 m3 during this period of time. Results from simulated scenario illustrated that, due to the extreme water scarcity situation,
industry in Beijing would still face a serious water deficit problem even with a very optimistic scenario for the future. 相似文献

Hydrocarbon and elemental carbon signatures in a tropical wetland: biogeochemical evidence of forest fire and vegetation changes 总被引:2,自引:0,他引:2
Evidence of changing vegetation in the tropical wetland (Rawa Danau, west Java, Indonesia) over the past 7428 years is illustrated by elemental (soot) carbon (EC) and n-alkane composition of sedimentary geolipids. In this study, vegetation changes and relevant controlling factors (e.g. forest fire and climate change) were documented on a decadal to centennial scale. The n-alkane composition that changes with depth might record changes in sources of organic matter (OM) in the wetland. The presence of EC (0.01–0.24% of organic carbon: OC) during late (0–1700 cal. year BP) and mid (3500–4500 cal. year BP) Holocene (at depths 0–50 cm, and 160–210 cm) indicated that large-scale forest fires severely affected the tropical vegetation. The hydrocarbon indices (CPI: carbon preference index, MCN: mean carbon number, and HVI: hydrocarbon vegetation index) significantly correlated with one another while a comparison of EC profile with the profiles of hydrocarbon indices indicated that n-alkane composition of the geolipid in lake sediment could record signatures of changes in catchment vegetation. Forest fire and vegetation changes might be related to regional climatic shifts relating to ENSO activity as well as being influenced by human influences. 相似文献

Heavy metal soil pollution takes place when the metal concentration of soil exceeds natural background level and causes ecological destruction and deterioration of the environment.In the present study,a pot experiment was conducted to evaluate the effect of chromium-contaminated soil in sunflower(Helianthus annuus L.)growth attributes.Three different levels of chromium(Cr)i.e.,20, 40,and 60 mg/kg were applied to three varieties of sunflower(G-3,G-9,and G-59).The results of morphological,chemical,and yield p... 相似文献

Awareness, Preparedness and Adjustment Measures of River-bank Erosion-prone People: A Case Study 总被引:2,自引:0,他引:2
MUHAMMAD Z. MAMUN 《Disasters》1996,20(1):68-74
People prone to the effects of river-bank erosion are well aware of the hazard they face, but see it as an unavoidable evil. Communities' lack of success in combating erosion can be attributed to their poverty and to their not knowing about any means to mitigate its effects. Households in safer areas have reduced their dependency on agriculture and developed more scope for non-farm activities, however, this is often difficult given the limited development of local enterprise. The major parameters that influence the adjustment measures after erosion are the education, skills, occupation and financial state of those affected. Those most vulnerable are households very much dependent on agriculture: for them resettlement to distant urban areas is not an option. 相似文献

Investigation of groundwater quality in hardrock terrain using Geoinformation System 总被引:1,自引:0,他引:1

Two hundred sample sites were selected systematically and samples were taken for a baseline study to understand the geochemistry of the groundwater and to assess the overall physicochemical characteristics. Sampling was carried out using pre-cleaned polyethylene containers. The physical and chemical parameters of the analytical results of groundwater were compared with the standard guideline values recommended by the World Health Organization for drinking and public health standards. Thematic maps pertaining to TDS, EC, Cl, NO3, SO4, and Na were generated using Arc View 3.1 platform. Results showed that most of the locations are contaminated by higher concentration of EC, TDS, K?+?, and NO $_{3}^{\;-}$ . Major hydro-chemical facies were identified using Piper trilinear diagram. Based on US salinity diagram, most of the samples fall in the field of C3-S1 indicating high salinity and low sodium water, which can be used for almost all types of soil with little danger of exchangeable sodium. Majority of the samples are not suitable for domestic purposes and far from drinking water standards. However, PI values indicate that groundwater is suitable for irrigation. 相似文献
