祁连山地区气候条件对牧草生长脆弱性影响研究

用多年气象资料和地理信息,分析了祁连山区气候资源概况及气候对牧草生长的脆弱性影响时段和水、热条件的影响敏感度,并建立了水、热综合影响指数,提出降低牧草生长脆弱性,主要从保持牧草结构合理性和多样性入手,减轻牧场人为不利干扰,增强有效干预,根据当地气候规律,增加"草地-气候-畜牧"系统转化驱动力,合理开发气候资源,提高耦合量,为牧草提供良好的生长、恢复环境,取得好的生态、经济效益.

A study on the influence of climatic condition of Qilian mountain area on the frangibility of grass growing

Based on the secular meteorological data and geographic data, the general situation of climatic resource, the periods of climate affecting the frangibility of grass growing and the degree of sensitivity of influence of water and heat condition have been analyzed. The influence index of water and heat to grasses have been set up. It is suggested that, the methods of keeping grass growing strongly are to keeping a rational and diversified structure of grasses, decreasing the harmful interference on the grassland and increasing the effective interference on grassland, according to the local climatic conditions to increase the transferring driving force of grasses-climate-animal husbandry system , exploiting climatic resource properly and increasing the coupling quantity, providing better condition for grass growing and gaining better ecological and economic efficiencies.
