发达国家学者认为乡村贫困最显著的特点是其具有隐藏性,即贫困人口的真实情况被平均统计数据所表现出的乡村发展状况所隐藏。本文以广东省连州市为例,基于平均统计数据和贫困人口数据,采用量图分析法和贫困发生率法分析乡村贫困的空间特征,并将两者进行对比。研究发现,基于平均统计数据的乡村经济发展水平空间差异并未真实地反映贫困人口的空间差异,一定程度上将贫困人口隐藏。这一结论与研究区地方发展背景密切相关,也可为现
With globe warming,road safety will change dramatically,especially within the Qinghai-Tibet Plateau permafrost regions.Because of higher elevation and better atmospheric transparency,the Qinghai-Tibet
Microorganisms in permafrost can live in cold environments due to coadapted physicochemical processes in this environment.In this paper,the relation between microbial number and soil physicochemical p
This paper analyzes the characteristics of climate,geology and geomorphology,vegetation,and sand dune distribution in the Cuonahu Lake area beside the Qinghai-Tibet Railway.The types and causes of rai
Based on remote sensing snow water equivalent(SWE) data,the simulated SWE in 20C3M experiments from 14 models attending the third phase of the Coupled Models for Inter-comparison Project(CMIP3) was fi
Using the snow cover fraction(SNC) output from eight WCRP CMIP3 climate models under SRES A2,A1B,and B1 scenarios,the future trend of SNC over East Asia is analyzed.Results show that SNC is likely to
Based on daily data sets of 17 meteorological factors during the period of 1954-2005 for 60 gauge stations distributed over Gansu Province of China and the corresponding dust storm records,the dust st
