【摘要】 对陕西秦巴山区垂直自然带的土地结构与演替研究，经过４次野外考察和１５个典型地段的填图、观察和分析，把秦巴山区分为秦岭北坡、秦岭南坡和大巴山北坡３个地区，对每个地区不同的带层，通过图件分析、数学计算和土地质量评价，针对土地类型的结构格局、选取代表性的２５个土地类型样本作演替模式模拟，并实现了通过计算机和ＧＩＳ支持的土地结构系统动力学仿真摸拟和模型建造．更多还原

【Abstract】 A study on land structure and succession of verticol zones in Shaanxi Qinling -Bashan mountainous area is a project subsidized by the National Natural Science Fund Committee.After having done 4 time of field survey, analyzed and mapped in 15 typical sections,Qinling-Bashan mountainous area are diuided into 3 regions such as northern slope of Qinling, southern slope of Qinling and northern slope of Dabashan.In differnt vertical zone of each region,successive models are imitated of representative land types selected according to the structure patterns of land types. Also the structure patterns and succession medels are studied of different region and different vertical zone in Qinling-Bashan mountainous area by the way of system-dynamical imitation and model constraction of land strcture which are supported by computer and GIS.更多还原
