The glaciers of central Asia provide suitable locations from which to recover continuous, high-resolution glaciochemical records on a continental scale. Although the glaciochemical investigations undertaken to date in central Asia are few in number and limited in terms of spatial coverage and length of record, some preliminary observations can be made concerning regional and seasonal trends in snow chemistry in this region. The sodium chloride ratio for most snow samples collected in central Asia approaches the ratio found in sea water (0.86 in μeq kg−1), reflecting a marine source for these constituents. Sodium and chloride concentrations are, on average, 3–10 times higher in the Himalayas than in the Karakoram, demonstrating the greater influence of monsoonal sources of moisture in the Himalayas. Very high sodium concentrations from Khel Khod Glacier probably reflect a local crustal source from surrounding ice-free areas. Low nitrate concentrations were found in snow collected from the southern margin of the Himalayas and high concentrations in snow deposited on the north margin of the Himalayas. This strong regional trend in the spatial distribution of nitrate suggests the influx of continental aerosols, rich in nitrate, originating from the arid regions of central Asia. High calcium concentrations measured in snow from Mount Everest and the north-west corner of China are also indicative of dust derived from the arid regions of central Asia. Very high sulfate concentrations found in snow from the Tien Shan and the Bogda Shan most likely reflect local anthropogenic sources. The altitude effect on isotopie composition is not apparent from snow samples collected in central Asia. Understanding the processes which control the chemical content of snow, the local-to-regional scale complexities, and the seasonal variability are fundamental steps necessary to assess the potential for recovering representative long-term glaciochemical records from central Asia.

Water is biologically essential to all life. Without an adequate supply plants and animals soon perish. But an abundant and assured supply of fresh water is also an economic and social necessity to modem industrial societies which withdraw prodigious amounts of it, chiefly for industrial, agricultural, and municipal purposes. Massive water withdrawals are particularly essential in arid regions where irrigation has been extensively developed. However, since irrigation is a major consumptive user of water (i.e., a large proportion of water withdrawn is not returned directly to the supply source), rivers and ground water suffer significant depletion with attendant ecological, economic, and social consequences.

Статья посвящена Политике Политбюро ЦК КПСС в отношении населения советской Центральной Азии в последнее десятилетие существования Советского Союза. Методологическая и теоретическая неразбериха, эклектика, откровенный субъективизм, скрытый догматизм стали характерными чертами современной историографии, которая уводит все дальше от реального исторического процесса, который происходил тогда в этом регионе под влиянием различных факторов. Характеризуется экономика и уровень жизни населения этого региона в канун перестройки, перспективы Центральной Азии, духовная жизнь, национальное самосознание, замыслы Ю.А. Андропова, действия М.С. Горбачева и республиканских руководителей в условиях начавшейся перестройки, сильные противоречия в высшей партийной номенклатуре. The article is dedicated to the Central Committee Politburo’s policy towards the population of Soviet Central Asia in the last decade of the U.S.S.R.’s existence. The methodological and theoretic chaos, eclecticism, open subjectivism, and concealed dogmatism became characteristic traits of contemporary historiography, which leads us farther and farther away from the real historic process that took place in the region, unraveling under certain factors. The article characterizes the region’s economy and the population’s level of life at the dawn of the Perestroika, Central Asia’s perspectives, its spiritual life, national self-awareness, Y. Andropov’s plans, M. Gorbachev’s and the republican leaderships’ actions during the Perestroika, as well as the strong inner contention in the Communist Party’s top nomenclature.
