选取新疆维吾尔自治区14个地(州)为研究对象,从农业气候干旱的敏感性和恢复力2个角度选取10个指标,对该区2001—2010年的农业气候干旱脆弱性进行评价。通过计算新疆各地(州)农业气候干旱脆弱度并绘制新疆农业气候干旱脆弱性区划图,分析该区农业气候干旱脆弱性的年际变化和地域分布特点及规律,初步探讨了其成因,提出缓解新疆农业气候干旱脆弱性的科学对策。结果表明:新疆各地区农业气候干旱脆弱度在时间尺度存在差异性变化,并存在显著地域性差异,总体呈现出“东高西低,南高北低”的分布状况,主要原因不仅有地形、水文和气候等自然环境因素的差异,还包括经济产业结构、科学技术研究、灌溉设施、全民意识和政策管理等社会经济因素,可以通过采用先进技术和高效管理措施、根据气候采取种植结构格局和方式、合理开采高效利用水资源、增强全民生态保护意识等措施,缓解干旱影响、降低区域干旱脆弱性。
In this paper, 14 prefectures and prefectures of Xinjiang Uygur Autonomous Region were selected as research objects. Ten indicators were selected from the perspectives of sensitivity and resilience of agricultural climate drought to evaluate the vulnerability of agricultural climate in 2001-2010 in this area. By calculating the agro-climatic arid fragility of Xinjiang (state) and drawing arid regional zoning map of agro-climatic arid climate in Xinjiang, we analyzed the interannual and regional distribution characteristics and laws of agro-climatic arid fragility in this area, discussed its causes and proposed mitigation Scientific Measures of Drought Vulnerability in Agricultural Climate in. The results showed that there was a significant regional difference in the vulnerability of agricultural climate in different regions of Xinjiang in the time scale, and there was a significant regional difference. Overall, the distribution of the “high in the east and the low in the west and low in the south in the south” was mainly due to Topography, hydrology and climate, as well as socioeconomic factors such as economic and industrial structure, science and technology research, irrigation facilities, national awareness and policy management. By adopting advanced technologies and efficient management measures, planting structure can be adopted according to climate Pattern and mode of exploitation, rational exploitation of water resources to enhance the awareness of ecological protection of all people and other measures to ease the impact of drought and reduce regional drought vulnerability.
