我们研究了美国西南部荒漠生态系统中土壤养分的空间分布，以检验荒漠灌木入侵半干旱草原与灌木下“肥力岛”的发展有关的假设。在新墨西哥州奇瓦瓦沙漠的草原上，35%-76%的土壤氮变化是在远处发现的
We examined the spatial distribution of soil nutrients in desert ecosystems of the southwestern United States to test the hypothesis that the invasion of semiarid grasslands by desert shrubs is associated with the development of ''islands of fertility'' under shrubs. In grasslands of the Chihuahuan Desert of New Mexico, 35-76% of the variation in soil N was found at distances
