Abstract

To make better use of the land, the regional climate response to vegetation change with oasis-desert-nesting structure in sensitive climatic area was studied in this paper. Three vegetation change experiments with different oasis-desert-nesting structure were designed and the differential charts between control and sensitivity simulation run were made. The results indicated that for oasis-desert-nesting structure, whose width reached certain width so as to engender local circulation, such as EXP1 and EXP2, its width change mainly affected intensity of climatic response while its complexity affected spatial distribution of climatic response. For commensurate mosaic oasis-desert nested structures in the same sensitive area, they had the same distribution type of climatic response but different intensity. EXP1, EXP2, and EXP3 presented that certain complexities can make nesting fields appear with a whole-field characteristic; there were different climate response to vegetation change between sensitive climatic area and ordinary one, the former with greater response than the latter.
