发展以卡普恰盖水库为基地的灌溉农业

生产力布局的改善是发展国民经济的迫切问题之一。苏共26大提出下列措施的重要目的是:“各加盟共和国与各经济区经济发展进一步专业化和按比例发展的基础上,改善生产力布局,提高社会生产效益”。哈萨克斯坦已做出了计划:“在开发自然资源和发展燃料动力与原料基地方面的巨大工程”。     

Foraminifera as indicators of marine pollutant contamination on the inner continental shelf of southern Brazil

Analyses of living foraminiferal and environmental parameters near an outfall at Mar Grosso Beach (Laguna, SC, Brazil) demonstrate its usefulness as indicators of domestic sewage pollution. The low species diversity may be due to sand accumulation in the central part. Higher diversity was noted closer to the mouth of Laguna estuarine system where reduced salinity and higher temperatures indicate freshwater influence, suggesting a relationship between increased diversity and greater availability of terrestrial food. On the basis of foraminiferal diversity and average coliform count the higher values are closer to the mouth of the estuarine system and under the influence of the outfall. Due to the effect of local hydrodynamics, the particulate organic waste derived from the outfall does not settle down locally, and thus, do not accumulate nearby. Our hypothesis is that the fine material derived from the outfall is accumulating on the southwestern and northwestern parts of the beach.     

世界大洋表层水温年际距平的分类

将世界大洋表层水温（ＳＳＴ）多年观测资料（ＣＯＡＤＳ）采用时间、空间状况分级分析方法进行了分类，得到了世界大洋ＳＳＴ距平时间、空间变化的样本。划分并了太平洋和大西洋中出现的同步和准同步偶极子遥相关的几种类型；划分出了世界大洋ＳＳＴ距平的全球模态。该模态在世界大洋的整个近赤道带有其独特的形式，而且与近海面大气压全球模态的时间相关性极好，并能描述Ｅｌ－Ｎｉｎｏ现象。
