内蒙古东北部天然牧草生态气候适应性研究

应用积分回归、模糊数学中隶属函数和地理信息系统,对内蒙古东北部的天然牧草进行分区生态气候适应性综合评价。分析表明:牧草的自然生态适应性在半干旱、干旱环境中明显不如湿润、半湿润地区;对天然牧草的资源总量、生态系统进行了系统辩识;以定量、客观的方法分析和评价牧草气候资源区域分布特征,揭示出了资源的总体状况和各气候生态要素间的相互匹配情况。可为制定畜牧业发展规划提供决策依据。

Ecological adaptability of natural pasture to climate resource in northeast Inner Mongolia

By using the methods of integral regression,subjection function and geography information systems,this paper appraises synthetically the ecological adaptability of natural pasture to the climate resource in north-east Inner Mongolia.The results showed that the adaptability of natural pasture was better in semi-humid and humid areas than in semi-arid and arid areas.Moreover,the total climate resource and ecosystem of natural pasture is synthetically evaluated.Based on the analysis of regional distribution features of climate resource,the matching relation between total resource status and various climatic ecological elements is discovered.It may lay foundations to establishing the development programs of animal husbandry,eliminating the conflict of forage and animals and adjusting measures to local conditions in scientific breeding.
