中文摘要	选择干旱内陆河石羊河流域为研究区,以流域内水资源和土地资源利用优化为目标,依据累积耗费距离理论,采用最小累积阻力表面(MARS)和耗费距离表面(MCR)模型, 借助表面扩散技术,研究了流域水土资源类型间进行能量交换、传递的阻力大小和耗费阻力空间分区,并进行了空间统计分析。结果表明: 石羊河流域代表水土资源的生态核心源为河网、其他水域、耕地和建设用地4类,其中建设用地累积耗费阻力值最大,对生态系统能量流动和传递阻碍作用最大,河网累积耗费阻力值最小; 根据水土资源配置方法和分区原则可划分为5种类型: 重点优化配置区、有待优化配置区、重点关注区、关注区、生态治理与保护区。需要进行水土资源优化配置的区域在重点优化配置区,这些区域集中在绿洲核心区,且承载了85%以上的城镇和人口,因此要扩大绿洲边缘区以防止外围荒漠逼近,绿洲与荒漠交接区要大力植树造林,提高水源涵养能力并减少耗水作物种植,使抗生态风险能力进一步提高。
英文摘要	Taking the optimization of water-soil resources as an objective,the energy exchange and transfer resistance,and cost resistance spatial distribution of the water-soil resources in Shiyang River basin were analyzed according to the minimum accumulative resistance surface,the accumulative cost resistance model and the surface dissipative technology. The results showed that the ecological core sources of water-soil resources were river net,other water areas,croplands and construction lands. The maximum value of accumulative cost resistance was found in construction lands which had the biggest resistance to energy flow and transfer of ecosystems. In contrast,the river net had the minimum cost resistance. According to the configuration methods and division principles of water-soil resources,Shiyang River basin was divided into five types,i. e.,the key areas to be optimized,areas waiting for configuration optimization,the importantly concerned areas,concerned areas,and ecological improvement and conservation areas. The key areas to be optimized are mainly distributed in Minqin and Wuwei oases that carry more than 85% of towns and population. Some measures should be taken to improve the ability of water conservation and to reduce ecological risk,for example,increasing oasis area in fringe,afforestation in the transition zone of oasis and desert and reducing planting water-intensively consuming crops.
