Shuitu Baochi Xuebao, 2005 丘陵、中低山区(海拔<1 500 m)是经济林果木发展的主要适生区域,亦是人类活动最频繁的区域,生态系统脆弱,一旦土壤地被物遭破坏,极易引起严重的水土流失.通过在四川盆地紫色土桃园地和盆边山地黄壤茶园地设置16个径流场,进行4种除草处理,应用不同除草方式调控水土流失试验1年,结果表明(1)除草试验处理的土壤侵蚀量和养分(N,P,K,OM)流失量排序是耕作除草＞草甘膦除草＞克无踪除草＞割草覆盖(CK).(2)除草试验处理的土壤侵蚀量与传统耕作除草相比较,坡度25°和坡度10°的桃园地应用草甘膦除草 ...

野生动物学报, 2014 2013年8月,在北京动物园马来貘馆,采用瞬时扫描取样法、焦点动物取样法和全事件取样法,对5只马来貘的行为和室外运动场空间的选择利用进行了研究。结果表明,马来貘在室外运动场主要使用草地、土地、深水水池和水泥地,较少使用浅水地面,回避乱石地; 运动型刻板行为多发生在门口或角落处的水泥地面上。为躲避游人干扰和日光暴晒,马来貘对室内的利用强度显著高于室外(P=0.011)。马来貘在室外运动场将较多的时间用于卧息、游泳和走动,其次是站立、刻板行为和采食,仅将很少的时间用于其他行为(包括饮水、排便、嗅闻、惊跳 ...
