Inner City regeneration: perspectives on the G.E.A.R. Project

Government responses to the problems of the inner city currently focus on comprehensive programmes of positive discrimination. The first and most extensive is the G.E.A.R. project in Glasgow. Regular monitoring of the effectiveness of such large‐scale initiatives is essential. If the physical and social aims of such policies are to be realised, assessments must utilise both objective and subjective indicators.     

Local economic development — the changing public/private sector relationship

The paper examines changing approaches to local economic development in the period since 1974. Initially, it proposes an ‘orthodox’ model of local economic development policies which emphasised the provision of a better industrial fabric, and of financial assistance to small, inner city firms. It suggests three recent directions of change in emphasis from this orthodox model: help in the creation of new entrepreneurs; replacement of public sector by private sector action; local authority shareholding in local firms by use of Enterprise Boards. Each approach makes different assumptions about the public/private sector relationship, the last two involve a more explicitly ideological stance on this issue.     

内蒙古赤峰地区草麻黄资源的分布及利用

本文论述了内蒙古赤峰地区草麻黄的分布和生态特性。草麻黄从东南至西北受气温和降水等因素的影响,在东南部丘陵沙地干草原区集中分布;在中部低山丘陵干草原区呈零星分布,在西北部山地草甸草原区无分布。草麻黄对干旱的环境条件适应能力强,具有耐干旱、耐沙湿、耐高温、耐寒、耐贫瘠和不耐水湿等生态特性。本文对如何保护与合理利用草麻黄资源,提出了建议。     

内蒙古农业灌区夏、秋浇的氮磷流失变化

通过对内蒙古农业灌区引黄灌溉的2次主要大规模灌溉（夏浇、秋浇）的跟踪监测,研究了农业灌区的氮磷流失情况.分析了2次灌溉期的各引水渠和排水渠中总氮（TN）、氨氮（NH4＋-N）、硝氮（NO3--N）、总磷（TP）、溶解性无机磷（DIP）、溶解性有机磷（DOP）、颗粒磷（PP）的变化情况.研究表明：夏浇时,由于植物吸收、灌水量小等因素,基本不产生污染.而秋浇期间,由于灌水量大、土地裸露成为非点源污染产生的主要时期.在对第8排域的TN、TP的连续监测中发现,排干沟中的总氮总磷含量基本维持在4.16mg.L^-1和0.1725mg.L^-1,且氮为主要的污染控制因子;排干沟中的N/P为24,排入乌梁素海中极易引起水华发生.结合河套农业灌区的自然条件、耕作方式等因素,综合分析了河套灌区在夏浇及秋浇时期的非点源污染产生过程及污染特点.为该地区非点源污染管理和控制提供科学依据.     

内蒙古地区矿区总体规划开展生物多样性评价的情况和建议

通过整理分析内蒙古矿区总体规划环评,分析生物多样性现状评价情况,提出发展内蒙古矿区规划环评巾生物多样性评价的几点建议。     

黄河宁蒙河段突发性水污染事件中应急监测探讨

草地畜牧业雪灾脆弱性评价 --以内蒙古牧区为例

从综合减灾和区域可持续发展的角度，建立了雪灾脆弱性评价指标体系及评价模型，并从雪灾区域孕灾环境敏感性以及区域畜牧业承灾体对雪灾的适应性两方面，对内蒙古雪灾脆弱性进行了评价。研究结果表明：内蒙古牧区雪灾脆弱性存在若明显的地域差异，中西部牧区比东部牧区脆弱性大，北部牧区比南部牧区脆弱性大，并且近10年来脆弱性提高的旗县明显增多，草地季节性干旱、北方干旱化以及草场超载过牧、退化加剧是畜牧业雪灾脆弱性呈增加趋势的直接原因。     

可持续发展与草原生态环境保护——以内蒙古草原区为例

草原具有自然和社会两方面的功能，在实现这些功能的过程中，应该遵循可持续性发展原则来维持健康的草原。草原的自然功能是社会功能的基础和保障，草原的社会功能是自然功能的延伸和发展，社会功能的发挥是建立在自然功能实现基础之上的。内蒙古地区在发展过程中要以科学发展观为指导，把建设社会主义新牧区的任务与草原发展的丰富内涵结合起来，加强草原生态环境保护，建设环境友好型和资源节约型社会。     

内蒙古煤矿环境地质问题及其防治对策研究

煤炭是内蒙古最具优势的矿产资源 ,其产值几乎占到该区工业产值的一半。由于历史及政策等因素的影响 ,煤矿开发破坏矿区环境资源、诱发地质灾害和导致环境污染。不同地域矿山开发诱发的环境地质问题不同 ,露天和地下不同的开采方式诱发不同的环境地质问题。国有大中型老矿区地面塌陷问题较为严重 ,成为制约矿山持续发展的主要因素之一。乡镇及个体小煤矿“只开发 ,不治理”加剧了矿山地质环境的恶化。在西部大开发中 ,要吸取“先开发 ,后治理”的历史教训 ,走资源合理开发利用与矿区生态环境保护的绿色矿业之路     

Desert pastoralists’ negative and positive effects on rare wildlife in the Gobi

In arid regions of the developing world, pastoralists and livestock commonly inhabit protected areas, resulting in human–wildlife conflict. Conflict is inextricably linked to the ecological processes shaping relationships between pastoralists and native herbivores and carnivores. To elucidate relationships underpinning human–wildlife conflict, we synthesized 15 years of ecological and ethnographic data from Ikh Nart Nature Reserve in Mongolia's Gobi steppe. The density of argali (Ovis ammon), the world's largest wild sheep, at Ikh Nart was among the highest in Mongolia, yet livestock were >90% of ungulate biomass and dogs >90% of large‐carnivore biomass. For argali, pastoral activities decreased food availability, increased mortality from dog predation, and potentially increased disease risk. Isotope analyses indicated that livestock accounted for >50% of the diet of the majority of gray wolves (Canis lupus) and up to 90% of diet in 25% of sampled wolves (n = 8). Livestock composed at least 96% of ungulate prey in the single wolf pack for which we collected species‐specific prey data. Interviews with pastoralists indicated that wolves annually killed 1–4% of Ikh Nart's livestock, and pastoralists killed wolves in retribution. Pastoralists reduced wolf survival by killing them, but their livestock were an abundant food source for wolves. Consequently, wolf density appeared to be largely decoupled from argali density, and pastoralists had indirect effects on argali that could be negative if pastoralists increased wolf density (apparent competition) or positive if pastoralists decreased wolf predation (apparent facilitation). Ikh Nart's argali population was stable despite these threats, but livestock are increasingly dominant numerically and functionally relative to argali. To support both native wildlife and pastoral livelihoods, we suggest training dogs to not kill argali, community insurance against livestock losses to wolves, reintroducing key native prey species to hotspots of human–wolf conflict, and developing incentives for pastoralists to reduce livestock density.
