从环境-社会系统的角度看"建设和谐社会"

环境-社会系统的三元结构是指人、社会和自然三元。可持续发展取决于对这三元运动机制的协调。从环境-社会系统的视角看。可持续发展是指通过三种生产的和谐运行与环境—社会系统的稳定演进．获得“经济-社会-环境”整体的高效益。人类社会发展的两大基本矛盾是资源生产的矛盾和资源配置的矛盾．因此。建设和谐社会的关键在于：在争取“人-社会-自然”和谐演进的前提下。处理好人与社会、人与自然、自然与社会以及自然的、社会的方方面面的“关系”。     

Specific features of the allozyme structure of dandelion populations under conditions of radionuclide and chemical contamination

A study of allozyme spectra has been performed in dandelion cenopopulations growing for a long time under conditions of chemical pollution (the zone of the Nizhnii Tagil Metallurgical Plant, NTMP) or radioactive contamination (the zone of the Eastern Ural Radioactive Trace, EURT). Cenopopulations from the NTMP and EURT zones and from the background area differ significantly in the qualitative and quantitative composition of allozyme phenes. An analysis of clonal diversity has shown that all cenopopulations are phenogenetically unique. The genesis of each cenopopulation proceeded in a specific way: they had different sets of progenitor plants, whose descendants varied genetically in the course of their reproduction and more or less successful colonization of habitats, undergoing selection under the impact of natural environmental factors and technogenic stress. An increased variability of enzyme systems, compared to the sample from the background area, and, as a consequence, reduced clonal diversity may be regarded as a trait common to populations exposed to chemical or radiation stress.     

Spatiotemporal population structure of the bank vole in a gradient of technogenic environmental pollution

Between 1998 and 2005, specific features of spatiotemporal distribution of small mammals in transformed habitats were studied using the example of the bank vole living in a gradient of chemical environmental pollution (the Middle Urals). Technogenic degradation of spruce-fir forests proved to entail significant changes in the spatial structure and abundance of vole populations. Differences in colonization of disturbed and intact territories by bank voles at different stages of population dynamics were revealed.     

Biodiversity of plants and soils in landscapes adjacent to the Buzuluk Pine Forest

The influence of the Buzuluk Pine Forest on biodiversity of plants and soil properties in adjacent territories has been studied. The results show that in the immediate vicinity of the pine forest, under the influence of the relatively mild and humid mesoclimate, natural phytocenoses are dominated by mesophytic species. Biodiversity reaches a peak at a distance of 17–18 km from the forest, which is explained by the presence of both mesophytes and xerophytes in the same phytocenosis. The same zone is also characterized by the maximum diversity of soil properties and structural complexity of the soil cover. Grass communities on ordinary chernozems with a homogeneous soil cover, typical of the steppe zone, are formed at greater distances from the forest.

湖北省1981年以来不同时间尺度气温的变化

详细分析全省７１站１９８１￣１９９４年与前２０年不同时间尺度平均气温差值的时空分布特征后发现，８０年代以来我省各地年均气温变化小，但相对地降温范围广，幅度大，且四季及逐月、甸格局发生重大调整，区域差异明显，其特点是冬久暖，夏久凉，春季前冷后暖，秋季反之、其中以夏凉春热最显著；鄂西山区四季均为负变温。     

江南丘陵县域农业资源利用与农业结构优化

针对南方红壤丘陵区农业资源利用的现状，以湖南省桃江县为例，应用灰色关联度模型定量分析了农业各部门产值对农业总产值的影响程度。结果发现，近50年来桃江县农业各部门的关联序列为：种植业（0.887 5）>牧业（0.760 2）>渔业（0.675 6）>林业（0.543 3）。种植业和牧业产值的变化对桃江农业总产值的波动起着主导作用。基于历史统计数据，利用灰色预测模型预测了2001~2005年5年内桃江县农业各部门产值的变化趋势。预测结果表明，各部门发展对农业总产值的关联度分别为：种植业（0.611 3）>渔业（0.358 7）>林业（0.347 6）>牧业（0.334 7）。比较两组关联序列可以清楚发现农业产业各部门的发展潜力。结合桃江农业资源和各部门的发展趋势，提出了桃江县农业结构优化调整的方向。

Provincial development plans in Zimbabwe: an analysis of their content,structure and methodology

Zimbabwean provincial plans were instituted to help in the achievement of the national goal of the creation of an egalitarian, socialist and integrated society. The national goal itself was adopted as an antithesis to the dualist society characterised by spatial, economic, social, politican and technological inequalities that Zimbabwe inherited from colonialism. This meant that provincial plans had to play both a functional (or growth allocating/distribution) and a territorial (or redistribution) role.

This paper reviews their role in achieving the national goal by examining their functions, content, structure and methodology. The paper concludes that because of their nature, provincial plans are not suitable tools for the achievement of the national goal.
