中文摘要	青海高原地形复杂、气候多变,农牧业气候资源类型也非常丰富。全球变化背景下,青海省呈现降水增多,气温升高、有效积温增加趋势,农牧业气候资源也发生了显著变化。本文采用青海省1961年-2008年全省54个气象台站观测资料,建立了青海省≥0℃年积温、7月平均气温、年降水量空间推算模式,得到青海省500m*500m网格化气候资源要素空间分布结果;结合青海省第二次气候资源区划指标,建立了≥0℃年积温、年降水、7月平均气温三级气候区划指标体系:以≥0℃年积温500℃、1500℃、2000℃、3000℃作为寒冷、寒温、冷温、凉温、暖温一级气候区的阈值;年降水50mm、200mm、400mm、600mm为极干、干旱、半干旱、半湿润、湿润二级气候区的阈值;7月平均气温6.0℃、11.5℃、13.5℃、18.0℃为种植青饲料、青稞或小油菜、春小麦、冬小麦三级气候区的阈值。按照上述指标,将青海省划分为39类气候区。对其中12类气候区的降水、气温及气象灾害等气候特征进行了分析,提出了各区适宜种植作物以及农牧业生产、发展建议。
英文摘要	Agroclimatic resources are an important component of agricultural natural resources and usually includes heat, water and radiation factors. Under global climate change across the Qinghai Plateau, there has been a trend of increasing precipitation, temperature, and effective accumulated temperature in the growth season. In this paper, the spatial reckoning model of accumulated temperature above 0℃, average temperature in July, and annual precipitation were established from 54 weather stations in Qinghai. A spatial distribution using a 500m * 500m grid of agro-climatic resources was produced. The accumulated temperature indices, 500℃, 1500℃, 2000℃ and 3000℃, were taken as first grade climate regionalization thresholds of frigid, chilly, cold, cool, and warm zones respectively. Annual precipitation indices of 50mm, 200mm, 400mm and 600mm were second grade climate regionalization thresholds for very dry, arid, semi-arid sub-humid and humid climate zones respectively. The July average temperature indices of 6.0℃, 11.5℃, 13.5℃, and 18.0℃, were the third grade climate regionalization thresholds. This index system consisted of accumulated temperature above 0℃, annual precipitation and average temperature in July. Qinghai was divided into 39 climate zones. Precipitation, temperature and other climatic characteristics of 12 climate zones were analyzed and included warm semi-arid plantation climate zone, cool semiarid plantation climate zone, cool semi-arid plantation-husbandry climate zone, cool semi-arid husbandry-forestry climate zone, cool arid plantation climate zone, cool very arid plantation climate zone, cool sub-humid plantation and husbandry climate zone, cold sub-humid husbandry-forestry climate zone, cold semi-arid plantation-husbandry climate zone, cold arid plantation-husbandry climate zone, frigid humid husbandry-forestry climate zone, and frigid sub-humid husbandry-forestry climate zone. Suggestions of suitable crops and developmental strategies for agriculture and husbandry in different zones are discussed.
