摘要:
随着全球气候变化,青藏高原的干旱化趋势愈加显现。根据1951—2010年气象灾害统计数据,利用GIS技术与自然灾害风险分析模型,基于2010年承险体脆弱性断面数据,分析了青藏高原农牧区210个县的干旱灾害风险要素空间分布特点,并对青藏高原农牧区进行了干旱灾害风险程度分区。研究表明:1.青藏高原农牧区旱灾中等以上(0.24~1.00)风险等级的区域面积总计为103.26×104km2,占农牧区总面积的63%。2.旱灾风险高值中心(0.44~1.00)总面积9.63×104km2,其中,西藏自治区占20%,青海省占77%,甘肃省占3%。3.旱灾风险低值区(0.00~0.15)总面积54.49×10...
Abstract:
With the global climate change, the aridification of Tibetan Plateau is becoming more and more obvious. Based on the 1951—2010 meteorological disaster statistical data and the vulnerability data of bearing body in 2010, and with the GIS technology and the natural disaster risk analysis model, this study comprehensively analyzed the spatial distribution of drought disaster risk factors for agricultural and pastoral areas within the Tibetan Plateau, and then used natural crack method to make drought disaster risk zoning. The results showed：1. The area with drought disaster risk of above medium level (0.24~1.00) is 103.26×104 km2，accounting for 63% of the total agricultural and pastoral areas；2. The area of highest value (0.44~1.00) center of drought disaster risk is 9.63×104 km2, and the area of Tibetan Autonomous Region, Qinghai Province and Gansu Province account for 20%, 77％ and 3% of the total highest value center area each respectively；3. The area of lowest value (0.00~0.15) center of drought disaster risk is 54.49×104 km2, and the area of Tibetan Autonomous Region, Qinghai Province, Yunnan Province, Sichuan Province, Gansu Province and Xinjiang Uygur Autonomous Region account for 52%, 6%, 1%, 35%, 1% and 5% respectively of the total lowest value center area each. So the situation of drought disaster for agricultural and pastoral areas within the Tibetan Plateau is severe.
