THE BALANCE BETWEEN SUPPLY AND DEMAND OF WATER RESOURCES AND THE WATER—SAVING POTENTIAL FOR AGRICULTURE IN THE HEXI CORRIDOR

The Hexi Corridor is an important base of agriculture development in Northwest China. According to recent statistics, there are 65.94×10⁸m³ of water resources available in the Hexi Corridor. At present, net consumption in development and utilization is 43.33×10⁸m³. Water supply and demand reach a balance on the recent level of production, but loss of evaporation and evapotranspiration is as much as 25.69×10⁸m³. So net use efficiency of water resources is 59%. Based on analyzing balance between water and land considering ecological environment at present, there exists the serious water shortage in the Shiyang River system where irrigation lands have overloaded. There is a comparative balance between supply and demand of water resource in the Heihe River system; and the Sule River system has some surplus water to extend irrigation land. Use of agriculture water accounts for 83.3% and ecological forest and grass for 6.9%. The Hexi Corridor still has a great potential for water saving in agriculture production. Water-saving efficiency of irrigation is about 10% by using such traditional technologies as furrow and border-dike irrigation and small check irrigation, and water-saving with plastic film cover and techniques of advanced sprinkler and drip/micro irrigation etc. cansave more than 60% of irrigated water. Incremental irrigation area for water-saving potential in the Hexi Corridor has been estimated as 56% – 197% to original irrigation area. So the second water sources can be developed from water saving agriculture in the Hexi Corridor under Development of the Western Part of China in large scale. This potential can be realized step by step through developing the water-saving measures, improving the ecological condition of oasis agriculture, and optimizing allocation of water resources in three river systems.

Temporal and spatial variations in extreme temperatures in the Qilian Mountains-Hexi Corridor over the period 1960-2013

Based on daily maximum and minimum temperatures at 18 meteorological stations in the Qilian Mountains and Hexi Corridor between 1960 and 2013, temporal and spatial variations in extreme temperatures were analysed using linear trends, ten-point moving averages and the Mann-Kendall test. The results are as follows: The trends in the majority of the extreme temperature indices were statistically significant, and the changes in the extreme temperatures were more obvious than the changes in the extreme values. The trends were different for each season, and the changes in rates and intensities in summer and autumn were larger than those in spring and winter. Unlike the cold indices, the magnitudes and trends of the changes in the warm indices were larger and more significant in the Hexi Corridor than in the Qilian Mountains. Abrupt changes were detected in the majority of the extreme temperature indices, and the extreme cold indices usually occurred earlier than the changes in the extreme warm indices. The abrupt changes in the extreme temperatures in winter were the earliest among the four seasons, indicating that these temperature changes were the most sensitive to global climate change. The timing of the abrupt changes in certain indices was consistent throughout the study area, but the changes in the cold indices in the Hexi Corridor occurred approximately four years before those in the Qilian Mountains. Similarly, the changes in the warm indices in the western Hexi Corridor preceded those of the other regions.

敦煌西湖自然保护区湿地演化及驱动力分析

西湖国家级自然保护区位于河西走廊西端,是敦煌盆地人工绿洲的天然屏障。近几十年来,由于气候变化和人类水土资源过度开发,保护区生态环境持续恶化,湿地退化和沙漠化趋势日趋严重。本文运用多时相资源卫星遥感影像,解译分析了保护区湿地演化规律。结果表明：1980-2013年间有23个年份湿地处于快速退化状态,保护区湿地面积由1.72×10⁴ hm²减少到0.99×10⁴ hm²,减少了42.4%;保护区湿地的斑块数从32个增加到51个,平均斑块面积由537 hm²减少为213 hm²,湿地演化呈破碎化趋势。湿地分布质心向西南方向移动了11.59 km,湿地呈整体向西南缓慢移动的趋势。运用因子分析法对湿地演化的驱动因子进行了分类,并利用投影寻踪模型分析各驱动因子对湿地演化的贡献率,结果表明：下游湿地退化的根本原因是大规模引地表水和开采地下水灌溉,其次是气候变化引起的冰川退缩、径流量衰减。20世纪90年代,西湖保护区湿地处于相对稳定状态,建议敦煌地区耕地维持在20世纪90年代初的2.7×10⁴ hm²水平,或通过节水、调整作物结构和跨流域调水等措施,压缩引地表水和开采地下水水量,灌溉用水需控制在20世纪90年代初的用水水平。该研究成果可为自然保护区湿地保护和流域综合开发提供依据。

基于土壤地球化学分区的重金属污染风险评价——以山东省郯城县某镇为例

以郯城县某镇生态地球化学调查取得的土壤地球化学数据为基础,利用因子分析法将研究区划分为3个土壤地球化学分区,10个土壤地球化学亚区。每个土壤地球化学亚区的元素间彼此存在相关性,而重金属元素的含量往往决定了该土壤地球化学分区或亚区的污染状况。首次尝试以土壤地球化学分区为评价单元,对郯城县某镇耕地土壤中8项重金属污染状况进行了评价。结果表明,该区耕地土壤重金属元素含量属弱至低等变异程度,均一化程度较高,重金属污染风险低,但个别土壤分区存在Hg,Ni,Cr含量分异程度大,点位高于背景比例偏高的现象;单项污染指数中Ni,Cr的值相对偏高,表明存在单个因子人为污染的现象;内梅罗污染指数指示I-3亚区为该镇最高,存在一定的污染隐患;地累积指数指示了I-3亚区中Ni、II-1亚区中Hg的值均>1,为轻微污染等级。此次评价工作也表明,基于土壤地球化学分区的耕地土壤重金属污染评价结果与土壤环境质量评价图件反映的信息较为吻合。
