摘要

以高海拔脆弱生态环境下的藏羊为研究对象,利用1961—2017年逐日气象资料、承灾体脆弱性、孕灾环境敏感性以及社会经济条件等因子,结合灾害理论模型,通过ArcGIS空间分析工具,分析评估了该区藏羊生长发育不同时期气象灾害综合风险。结果表明:高海拔脑山地区羔育期和剪毛期风险较高,浅山或川区风险较低;打草期和配种期浅山、川区及河谷地带风险较高,而脑山地区较低。由此可见,地形因素是影响高海拔地区藏羊生长发育期的主导因子。

Abstract

Tibetan sheep in alpine fragile ecological environment was researched using the daily meteorological data during the period of 1961-2017,and the vulnerability of the sheep,environmental sensitivity and social and economic conditions were analyzed.The theory model of disaster,meteorological disaster risk estimation and ArcGIS spatial analysis were applied to lucubrate and estimate the sheep growth in different periods.The results showed that the risk in the alpine zone was higher in lambing and shearing periods but lower in the hills and on the gentle slope.In copulation and grass harvest periods,the risk was higher in the hills and valleys and on the gentle slope but lower in the nalpine zone.Thus it can be seen that terrain is a dominant factor affecting Tibetan sheep growth in the alpine zone.
