人口、资源、环境与经济发展之间的关系

自1991年,党中央每年在全国人大开会期间都召开各省、自治区、直辖市党政主要领导同志参加的计划生育座谈会,近几年来党中央陆续将环境与资源也列入了座谈会的主要议题。     

严重退化土地修复技术研究

开展严重退化土地修复技术研究,充分掌握严重退化土地的分布状况、影响机制,掌握先进实用的修复治理技术,在环境地质调查的基础上,利用先进的土壤改良技术,对重度盐碱化土地修复的适用性模式进行综合设计,并通过实验区建设,使这项修复技术得到推广,解决治理严重退化土地的难题,是本项研究的重点。     

城市地质工作开展的必要性

一、城市地质学的涵义 城市地质是专门研究城市建设与地质环境之间关系及相互作用的科学。是地质学与城市科学交叉而产生的边缘学科,是为城市建设和创造良好的城市环境而进行的地质工作。     

省国土资源厅向全系统发出号召——讲党性 树新风 优环境 促发展

为更好地贯彻落实省委关于在全省开展以“讲党性、树新风、优环境、促发展”为主题的作风建设活动的总体部署要求,近日,省国土资源厅制定了《活动方案》,号召全省各级国土资源部门以扩内需、保稳定、促发展为目标,进一步改进作风、提高能力、健全机制、形成氛围,为全省经济社会实现更好更快发展做出新的贡献。     

矿山地质环境治理存在问题及对策

矿山地质环境问题,是人类工程活动引发的各类环境问题中最主要的问题之一.矿产资源的开发极大地促进了经济繁荣、社会进步和人类文明,而相伴而生的大量矿山地质环境问题,不仅严重威胁人民的生命财产安全,而且严重影响区域乃至全国的经济社会的全面协调和可持续发展,甚至影响社会安定.     

关于完善我国矿山环境恢复治理保证金制度的思考

矿山环境恢复治理保证金制度是我国为保护矿山环境,督促矿山企业认真履行"谁开发谁保护,谁破坏谁赔偿,谁污染谁治理"的义务而制定的一项环境保护政策.该项制度时我国矿山环境的恢复治理,创建环境友好型、资源节约型社会具有重要意义,但在我国实施过程中还存在一些问题,文章就该项制度在实施过程中存在的问题进行分析并就进一步完善该项制度提出了相关建议.

Micromorphology of solonetzic horizons as related to environmental events in the Caspian Lowland

Micromorphology of solonetz species with special attention to natric horizon was studied in microcatenas at the Dzhanybek Research Station （northwestern Caspian Lowland）. The solonetzic （natric） horizon is easily identified, and it occurs at varying depths, which are the criteria for subdividing solonetzes into 4 species, namely, crusty, shallow, medium and deep. In this sequence, the depth of humus-accumulative horizons increases, and the upper boundary of salinity manifestations goes down. The following micromorphological features are assumed as typical for natric horizons： angular blocky microstructures with partially accommodated aggregates having sharp boundaries and narrow plane-like packing voids; b-fabric speckled in the aggregates＇ centers and monostriated at their peripheries merging into stress coatings; very few interpedal voids; organo-clay coatings; humus- enriched infillings; no calcite and gypsum pedofeatures. A complete set of ＂natric＂ features was found only in the crusty solonetz; the shallow solonetz lacks only illuviation coatings, while the medium and deep species have several modifications of fabric elements： blocky aggregates have a rounded shape and are penetrated by biogenic channels favoring their further biogenic reworking; plant residues became more abundant and diverse, and blackened tissues occur; illuviation clay coatings evolved into papules; stress coatings gave birth to striated bfabrics, thus maintaining a high plasma orientation. The thin sections of natric horizons made 50 and 20 years ago were examined to study the influence of environmental changes （increase in precipitation and rise of ground water table） on micropedofeatures. The following processes took place： （i） in the topsoil： humus accumulation and biogenic structurization; （ii） in the natric horizon - re-arrangement of clay coatings into micromass b-fabrics; and （iii） in the lower part of the natric horizon - development of pseudosand fabric, calcite and gypsum formation. The trends revealed are in good agreement with the environmental events.
