根据历史资料、野外调查数据及栽培试验，对野生洽草的生态适应特性进行了研究，对其利用现状进行了分析.结果表明：洽草（Koeleriacristata）的生态适应范围十分广泛，几乎遍及内蒙古除荒漠、草原化荒漠和寒温带针叶林区以外的其它各植物州.洽草生态适应性较强，可以适应腐殖质含量1~17%，C/N5~20，pH5.6~9.0的土壤；要求大气年降水150~500mm，≥10℃活动积温1600~3200的水热条件；海拔分布范围为820 m~3000m；具有良好的耐寒性.洽草是典型草原中优良的补充牧草，能够有效地补充牲畜对微量元素Fe、Ca、Mn等的需求.野生洽草叶型、叶色独特，具有春季返青早、成坪快、绿期长、草群低矮、密丛生、分蘖能力强、春秋两季坪用价值高等优良的地被植物特性，作为干旱半干旱地区城市雨养草坪品种具有巨大的开发潜力.
根據歷史資料、野外調查數據及栽培試驗，對野生洽草的生態適應特性進行瞭研究，對其利用現狀進行瞭分析.結果錶明：洽草（Koeleriacristata）的生態適應範圍十分廣汎，幾乎遍及內矇古除荒漠、草原化荒漠和寒溫帶針葉林區以外的其它各植物州.洽草生態適應性較彊，可以適應腐殖質含量1~17%，C/N5~20，pH5.6~9.0的土壤；要求大氣年降水150~500mm，≥10℃活動積溫1600~3200的水熱條件；海拔分佈範圍為820 m~3000m；具有良好的耐寒性.洽草是典型草原中優良的補充牧草，能夠有效地補充牲畜對微量元素Fe、Ca、Mn等的需求.野生洽草葉型、葉色獨特，具有春季返青早、成坪快、綠期長、草群低矮、密叢生、分蘗能力彊、春鞦兩季坪用價值高等優良的地被植物特性，作為榦旱半榦旱地區城市雨養草坪品種具有巨大的開髮潛力.

Based on Historical data,field survey data and cultivated test,studied the ecological adaptability characters of Koeleria cristata,analyzed its present situation of research. The results showed that: the ecological adaptability range of K. cristata is broad,it can distribute in the plant state except desert,steppe desert and cold temperate conifer-ous forest region in inner Mongolia. K. cristata can live in the soil with content of humus 1~17%,C/N5~20,pH5.6~9.0, require the precipitation of atmosphere 150~500mm each year,≥10℃active accumulated temperature1600~3200,it can endure the cold well,its range of height is 820 m~3000m.As a supplementary forage grass,K. cristata can effec-tively supply Fe,Ca,Mn to livestock.K. cristata has its own special leaf model and leaf color,it has well characteris-tics of groundcover plant with re-green early in spring,fast covering the base,long greening period,low turf clump, thick clump,strong ability of tillering,high lawn-value in spring and fall,it can be exploited as lawn which only live on rain in the arid and semi-arid region.
