【摘要】 1997—12～1998—07在山西五鹿山地区进行了铁矿区对褐马鸡（Crossoptilonmantchuricum）活动影响的调查．结果表明，褐马鸡的活动在铁矿出现前后有极显著的差异（t检验，n=38,p=0.003）．褐马鸡很少在铁矿周围出现，即使出现，距离铁矿大都在50m以外．对3个重点调查地点的观测结果表明，铁矿区对褐马鸡觅食活动的影响面积分别为17840，5246，13730m2．铁矿开采对褐马鸡的影响主要是它的屏障作用和降低了栖息地的连接度．更多还原

【Abstract】 Effects of iron mines on Brown eared-pheasant (Crossoptilon mantchuricum) were studied from December 1997 to July 1998. The results show that Brown eared-pheasant seldom occur around mines (t test, p<0.01). Even if occuring, it almost keeps more than 50m from the mines. Brown eared-pheasant’s feeding area is reduced due to iron mines’ exploration. At three sites, Liugeduo, Yanghuangshanggou and Beihuangshanggou, the reduced area is 17 840, 5246, 13 730m2 respectively. The effect of mines are mainly its "barrier effect" and reducing habitat integrity.更多还原
