摘要
在前人研究的基础上,从气温、降水及湿润指数三方面探讨了青藏高原地区气候状况,并分析了该地区气候变化对农作物生长的影响.结果表明,青藏高原地区与其他地区相比,气候变化大,随着全球气候变暖,该地区气温及降水总体上呈现增加趋势,高原植被好的区域气温变化小,但降水变化大,该地区近些年气温变化小,且气温呈现出逐渐增加趋势,对该地区农业生产是非常有利的,但还是有一些不适宜农业生产的地方,青藏高原地区应该因地制宣地种植农作物,促进农业的可持续发展.
Abstract
Based on previous research,climate status of Qinghai-Tibet Plateau was discussed from three aspects of temperature,precipitation and humidity index.Effects of climate change on crop growth were analyzed.Results showed that compared with other regions,Qinghai-Tibet Plateau had relatively great climate change.Under the situation of global warming,temperature and precipitation showed a rising trend in Qinghai-Tibet Plateau.Areas with relatively abundant plateau vegetations had slight temperature changes but great precipitation changes.Qinghai-Tibet Plateau had small temperature change in recent years; and the temperature showed a gradually increasing trend,which were helpful to agricultural production.However,there were still some disadvantages.Crop should be planted according to the local situation in Qinghai-Tibet Plateau,so as to promote the sustainable development of agriculture.
