摘要

农业旱灾的脆弱性评价是旱灾风险防范的重要基础.本文从脆弱性的定义出发,明确界定了旱灾脆弱性评价 的内涵,系统梳理了农业旱灾脆弱性区划评价和脆弱性曲线构建的方法,在此基础上,讨论了目前农业旱灾脆弱性评价 研究中存在的问题和未来发展的趋势,并指出未来农业旱灾脆弱性评价应在以下4个方面进行深入研究,1)未来农业 旱灾脆弱性评价应该逐步从定性的区划评价研究过渡到定量研究上;2)在区划评价研究中要重点加强指标权重确立的 科学性、合理性;3)在脆弱性曲线的构建中要加强对脆弱性曲线精度的验证和适用性的评价;4)综合利用多种评估手段 和地理信息技术,加强精细尺度的农业旱灾脆弱性评价.

Abstract

Vulnerability assessment of agricultural drought is an important foundation of risk prevention of drought. In the present work, the definition of vulnerability is explored, the connotation of the drought vulnerability assessment is defined, two categories of agricultural drought vulnerability assessment methods (zoning assessment and vulnerability curves) are summarized, the existing problems of current methods are discussed, and future research directions are pointed out. Quantitative methods of agricultural drought vulnerability assessment should be emphasized. In zoning assessment methods, researchers should pay attention on the objectivity and scientificity of index weight. During the process of construction of agricultural drought vulnerability curves, the precision and applicability of vulnerability curves are required. Finally, assessing drought vulnerability on finer scales (such as farmer-scale and grid-scale) will be another hotspot.

Key words

Agricultural Drought; vulnerability zoning; vulnerability curves; drought vulnerability
