滇池流域防护林体系建设对环境的保护作用

滇池防护林体系计划于2010年在14．783万公顷林业用地内建成，按推算可使全流域土壤侵蚀量减少20．75％，固土能力增加75．14％，入湖泥沙减少48．72％，入湖总磷、总氮减少48．72％，并能使全流域防护林不总量达到18443．8万吨。     

西昆仑库地北构造带两侧地质特征对比及其大地构造意义

根据新藏公路沿线实际观察资料及前人研究成果，着重通过库地北构造带两侧变质岩、岩浆岩及构造古环境特征的对比，以及对构造带中蛇绿岩的地质特征和形成环境的分析，初步探讨了该构造带的大地构遣演化。认为库地北构造带为古昆仑洋盆消减、封闭的最终位置，是形成于志留纪的板块聚合碰撞缝合带，代表着早古生代阶段塔里木板块的南部边界，也是控制塔里木盆地西南部和西昆仑山地区区域构造格架的重要构造带。     

喀喇昆仑山-西昆仑山地区的垂直自然带、环境和自然保护问题

喀喇昆仑山—西昆仑山地区属于青藏高原西北部寒冷干旱的荒漠、半荒漠地带,是连结高山荒漠和山地荒漠的关键区域。根据垂直自然带谱的基带及各分带的组合配置形式,可区分出干旱、极干旱、高寒干旱及高寒半干旱四种结构类型组。垂直自然带的区域变化明显,喀喇昆仑山与西昆仑山育显著不同,不仅南北翼有别,东西方向的递变也很突出,反映出大尺度的地域分异规律。全新世以来,干旱化的趋势十分明显,人类活动引起的环境问题突出,建议对雪岭云杉和昆仑圆柏等采取保护措施,并在羌塘高原腹地建立高原自然景观及野生动植物自然保护区。

Air Quality Status of an Open Pit Mining Area in India

This investigation presents the assessment of ambient air quality carried out at an open pit coal mining area in Orissa state of India. The 24-h average concentrations of suspended particulate matter (SPM), respirable particulate matter (RPM, particles of less than 10 m aerodynamic diameter), sulphur dioxide (SO₂) and oxides of nitrogen (NO_x) were determined at regular interval throughout one year at 13 monitoring stations in residential area and four stations in mining/industrial area. During the study period, the 24-h and annual average SPM and RPM concentrations exceeded the respective standards set in the Indian ambient air quality standard (NAAQS) protocol in most of the residential and industrial areas. However, the 24-h and annual average concentrations of SO₂ and NO_x were well within the prescribed limit of the NAAQS in both residential and industrial areas. A management strategy is formulated for effective control of particulate matter at source and other mitigative measures are recommended including implementation of green belts around the sensitive areas.     

Syndromes of Global Change: a qualitative modelling approach to assist global environmental management

A novel transdisciplinary approach to investigate Global Change (GC) is presented. The approach rests on the decomposition of the intrigue dynamics of GC into patterns of civilization–nature interactions (syndromes) by an iterative scientific process of observations, data and system theoretical analyses, and modelling attempts. We illustrate the approach by a detailed analysis of the Sahel Syndrome, which describes the rural poverty driven overuse of natural resources. The investigation is performed by (i) identifying relevant symptoms and interlinkages which are characteristics for this pattern, and (ii) a qualitative model representing the internal dynamics of the essential flywheel. The geographical patchwork of the regions affected by the syndrome which is obtained by global data analysis, proves the high global relevance of this pattern. The qualitative model is employed for an evaluation of basic policy strategies debated in the context of rural poverty driven environmental degradation. It turns out that a mixed policy of combating poverty and introducing soil preserving agricultural techniques and practices is most promising to tackle the syndrome dynamics.     

贫困的“物以类聚”：中国的农村空间贫困陷阱及其识别

理解贫困陷阱及其成因是理解减贫机制,进而理解贫困治理的基础。早期的实证研究注重从收入的角度研究农村贫困,较新的研究开始关注“空间外部性”对农村贫困的影响。然而,要正确识别农村的“贫困陷阱”,就需要对上述两个维度同时进行解释。鉴于此,运用中国县级层面的面板数据,从聚集与持久两个维度对中国的农村贫困陷阱进行了识别。研究结果表明：2006—2016年,中国农村的贫困空间格局几乎没有变化,并且贫困的空间分布与经济增长也并非是同步的,贫困县的分布主要与地形（坡度、海拔）因素有关;进一步研究还发现,中国的农村贫困具有持久性,贫困县收入存在低水平的均衡,贫困县与非贫困县之间存在收入的“俱乐部收敛”。本文揭示了空间外部性与农村贫困之间的关系,为正确评估经济发展与扶贫开发,合理制定区域反贫困瞄准机制提供了支持。
