摘要

过度的放牧压力降低了植被的基础面积值，也改变了植物的组成。本研究基于与天然水源的距离考察了放牧对牧场植被的大气圈效应。以土耳其地中海地区天然水源卡拉戈尔湖为研究对象，对其周围大气圈效应进行了评价。在距离湖泊0-1000 m、1000-3000 m和3000-5000 m三个不同的样地内测定了植被的变化。研究区基底面积的平均值分别为10.71%、14.46%和22.16%。平均烘干干草产量分别为639.0 kg hm -1、1542.9 kg hm -1和2146.3 kg hm -1。植被相似性指数表明，随着离湖距离的增加，植物组成发生了变化。站点1和站点3的相似性指数最低(30.31%)。

The Piosphere Effects of Livestock Grazing on Rangeland Vegetation in Ahir Mountain of Kahramanmaras Region

Excessive grazing pressure on rangeland vegetation reduces the basal area value of vegetation and also changes the botanic composition. This study examined the piosphere effects of livestock grazing on rangeland vegetation based on distance from a natural water source. The piosphere effects were evaluated around Karagol Lake, which is a natural water-source in Mediterranean region of Turkey. The changes in vegetation were determined within three different sites where sample plots were located at 0-1000 m, 1000-3000 m and 3000-5000 m away from the lake. The mean values of basal area in the study area were 10.71%, 14.46%, and 22.16% for three sites, respectively. The average oven-dry hay yield was 639.0 kg ha-1, 1542.9 kg ha-1, and 2146.3 kg ha-1, respectively. The vegetation similarity indices of the sites indicated that the botanic composition changed with respect to increasing distance from the lake. The lowest similarity index was encountered between the site one and site three (30.31%).
