中文摘要：

半城市化地区是普遍存在却难以精确量定的空间实体,现有划分方法往往难以兼顾空间要素指标和研究精度的匹配。以乌鲁木齐市高新区为研究区,在Landsat OLI遥感影像数据支持下综合使用3S技术,结合断裂点分析方法,根据用地指标断裂点的空间分布界定出半城市化地区的地域范围。结果表明,乌鲁木齐高新区半城市化地区呈星形发散状分布于老城区和郊区之间;经实地采样验证,上述方法可行,能为半城市化地区的空间界定研究提供新的途径。

英文摘要：

The peri-urban area does exist generally,but it is difficult to identify precisely. Current methods have some difficulty in combining spatial indicators with linkage of the research precision. Taking Gaoxin District of Urumqi as a study area,the spatial boundary of peri-urban area was identified using 3S technique based on remotely sensed images of Landsat OLI,and the break point analysis method combining with the position of the inner and outer boundaries of land-use indicators ’breakpoints. The results showed that peri-urban area in Gaoxin District of Urumqi appeared star radial divergent distribution between the old city and suburban districts. Using field sampling to verify,the results proved that the method was workable and offered a new way in the research on abstraction of peri-urban area.
