摘要
莎草科植物是黑颈鹤越冬期间重要的天然食物资源.通过比较人工种植在不同环境梯度下的3种莎草科植物地下块茎的鲜重表明:莎草科植物地下块茎重量在浅滩生境中显著比在陆地生境或者深水区生境中高(p<0.05);土壤紧实以及杂草都会对莎草科植物的生长起负面影响.在浅滩生境中,黑颈鹤出现在人工种植的莎草科植被区与天然环境下的莎草科植被区的数量没有显著差异(p>0.05),人工栽种莎草科植物是解决黑颈鹤越冬食物匮乏的一种有效的途径.
Sedges are the critical diet resource to Black-necked Crane during its overwintering period. By comparing the fresh weight of root of three sedge species which are planted in different environmen- tal grades, the results showed that the weight of sedge roots planted in shallow water body habitats were higher than those planted in land and deep water area（p 〈0.05 ） ,tight soil and abundant grass have negative impacts on the sedges On shallow water body habitats, there was no significant difference of the Black-necked Crane between planted sedge block and natural sedge block（p 〉 O. 05 ）. Sedge plant- ing is an effective approach to resolve the problem of shortage of diet to Black-necked Crane during its overwintering period.
