The environmental dimension of national security: A test of systems analysis methods

The systems approach permits us to analyze national security as a cluster of interconnected elements, in which the environmental dimension appears to be the most important one. The environmental problem is divided into two main aspects: environmental security per se and the impact of environment on the overall status of a nation's security. It is argued here that the quality of life and health serve as both the main objective and the principal criterion of environmental security in a social system. Indices of these two factors are used in this article as indicators of the state of this type of security. They confirm that vast areas of Russia, the Ukraine, and Central Asia (especially the Aral Sea region) should be considered as presenting a substantial risk to local people and even producing global impacts on both natural and man-made systems. Environmental factors that destabilize national security are also divided into two groups: those that impact social systems directly and negatively (mainly natural disasters) and technological and sociopolitical agents that cause indirect impacts, in both war and peace time, as well as in the civil and military sectors of the economy. Developments in the former Soviet Union (the Commonwealth of Independent States) are used as an illustration of the consequences that such impacts may have on the status of national security.

充分利用农业资源,发展我国粮食生产

我国粮食生产的制约因素较多。为了达到我国粮食产量稳定增长的目的,我们必须针对我国农业资源的特点,趋利避害,充分发挥其优势,挖掘生产潜力;搞好宏观调控,调动各方面的积极性,发展粮食生产。这样,2000年实观我国粮食总产量达到 5亿t,人均占有粮食400kg 的目的是可能的。     

MACROPHYTE STANDING CROP AND PRIMARY PRODUCTWITY IN SOME FLORIDA SPRING-RUNS1

ABSTRACT: A survey of 31 Florida spring-runs was conducted to estimate their submerged macrophyte standing crop and primary productivity. The standing crops of submerged vegetation were not significantly (p > 0.05) correlated to either total nitrogen (r = 0) or total phosphorus (r =?0.20) concentrations, but standing crops were significantly (p < 0.01) correlated to the percentage of the spring-run's water surface shaded by marginal vegetation (r =?0.76). Maximum daily rates of primary productivity were positively correlated with average submerged macrophyte standing crops (r = 0.81; p < 0.001) and inversely correlated with the degree of shading by marginal vegetation (r =? 0.43; p < 0.05).

青海省草地畜牧业可持续发展战略与对策

青海省有可利用草地3161×104hm₂,是我国五大牧区之一。在长期传统游牧畜牧业经营方式下 ,对草地缺乏有效的保护和科学的管理 ,片面追求牲畜存栏数 ,超载过牧现象普遍存在 ,导致草地退化问题严重 ,生态环境破坏 ,自然灾害频繁 ,畜牧业经济效益低下。在这样的基础上实施草地畜牧业可持续发展战略 ,需要执行科技兴牧 ,教育先行 ;强化畜牧业生产基础 ,经济效益和生态效益并重 ;大力促进畜牧业产业化 ,走商品化生产发展道路的方针。推行高效集约化经营的畜牧业生产模式 ,发展具有高原特色 ,具有市场竞争力的特色畜产品生产 ,在实现畜牧业向高效益产业转变的基础上顺利地实施生态环境治理和草地资源保护 ,从而达到畜牧业可持续发展的目的。
