人类活动对亚洲中部水环境安全的威胁
Threat of Human Activities to Hydrological Regime in Central Asia
摘要
Abstract
In the arid climate areas in Central Asia, the low-land area and plains hardly generate any surface runoff due to inadequate precipitation, yet relatively sufficient precipitation in the mountains forms streams flowing to the plains. These streams are the primary sources of surface water in oases and deserts, redistribute the limited surface water resources, recharge groundwater in the plains, and sustain the fragile and unique ecosystems in the oases and deserts. Such ecosystems have been under the serious pressure from human activities in recent decades. Expansion of farmland, cities and towns increases the consumption of surface water and groundwater, disturbs the natural hydrological regime, and threatens the sustainability of ecosystems in the arid areas in Central Asia. In this paper, the impacts of human activities on hydrological regime and ecosystem health in the arid areas in Central Asia are discussed based on the multi-year observed data, and some mitigation strategies are suggested.关键词
