以准噶尔盆地南缘梧桐窝子地区的10块弃耕地为研究对象。通过对弃耕地耕作历史及复生植被的调查,以“时空互代”的思路横向比较不同弃耕地上的植被。发现当周边生境接近似时,相似的历史耕作活动能够塑造出相似的弃耕地植被。最后一次耕种,特别是最后一次耕种的耕种面状况是影响当地弃耕地演替路径的重要因素。耕种时耕作面起伏度大,浇灌易造成局部积水,有利于幼苗早期发育需过湿生境才能完成生活周期的旱生植物定居。以弃耕后复生的柽柳数量为依据,比较当地退耕还林实施办法,探讨新的退耕还林途径。
Ten abandoned abandoned plots of Wutongwozi area in the southern margin of Junggar Basin were studied. Through the investigation of the abandoned farmland farming history and the reclaimed vegetation, we compare the vegetation on different abandoned lands horizontally with the idea of “time and space exchange each other”. It is found that similar historical farming activities can create similar abandoned farmland vegetation when nearby habitats are similar. The status of cultivated land in the last cultivation, especially in the last cultivation, is an important factor that affects the succession path of the abandoned farmland. Farming tillage surface undulating degree, easy to cause partial watering irrigation, early seedling development is conducive to wet habitat to complete the life cycle of xerophytes to settle. Based on the number of tamarisk rehabilitated after abandoning tillage, we compared the local implementation of returning farmland to forest and discussed the new approaches to returning farmland to forests.
