蔓延中的城市环境变迁在许多方面不利于青少年日常体力活动的参与，为此，需要了解其内在规律与机制，并提出科学合理的干预措施。该领域研究深入发展的关键在于数据分析定量化，而定量化的难点在于环境指标量化。针对目前研究以定性调查为主，地理信息系统（GIS）定量研究指标不够全面，在研究进展基础上对相关地理信息指标进行深入分析。研究认为：1）城市蔓延影响青少年体力活动主要集中在密度、土地利用、城市扩张形态、道路布局、通达性、可及性以及景观格局等地理特征；2）现有的城市环境影响青少年体力活动研究已涉及大部分地理特征类型；3）指标选取可参照多指标综合测量为主，各项地理特征均匀分布，不同体力活动类型有所侧重以及不同研究目的灵活应用等准则。

There have many aspects in environmental changes that negative for adolescent physi- cal activity in urban sprawl, so we need to understand its internal rules and mechanism that can proposes the science and reasonable intervention methods. The key of this study field develop-ment in-depth of lies in data quantitative analysis, and the difficulty of quantitative analysis is environmental indicators quantification. This article in respect to present study main on qualita- tive investigation, also geographic information system （ GIS ） quantitative indicators is not comprehensive enough, that analyzed the suitable geographic information indicators in detail. This paper point out that 1） urban sprawl affect youth physical activity mainly concentrated on the density, land use, urban expansion shape, road layout, walkability, accessibility and landscape pattern these geographic characteristics;2） the existing studies between built environmental and ado- lescent physical activity has been involved in most types of geographic characteristics; 3 ） indicators selection priority refer to multiple indicators comprehensive measurement, each types of sprawl char-acteristics uniform distribution, primary and secondary correspondent to different types of physical ac-tivitv , and flexible application different research purposes and so on.
