北京城乡空间发展模型:BUDEM2

Beijing Urban Developing Model: BUDEM2

自2009年北京空间发展模型第一阶段顺利完成以来,北京市范围内的地块尺度的空间数据(地块和建筑)和精细化的社会经济数据(居民和企业等)均有了大量的积累;同时,在技术方法层面也有了一定程度的发展,具备了进行微观尺度模型研究的条件。因此本文以北京市空间发展的大量数据为依托,直接面向北京城乡规划实践,对空间发展模型的理论和技术架构进行了深入研究,建立了一套多尺度、多维度的城乡空间发展模型:BUDEM(Beijing Urban Development Model)。该模型由土地开发模块(宏观与微观)、人口空间化与属性合成模块、居住区位选择模块、企业区位选择模块以及基于活动的交通出行模块构成,可以对城市扩张与再开发进行模拟,并进行相应空间政策的评估。

Since the accomplishment of Beijing Urban Developing Model （Phase 1） in 2009, we have accumulated more spatial data （include parcels and buildings） and socioeconomic data （residents and companies） in fine-scale level. Meanwhile, research methods developed to a certain extent. We have met the requirements of conducting micro-scale model researches. This article conducted deep studies in spatial development model theories and technical frameworks based on abundant spatial data in Beijing, and faced Beijing urban ＆ rural planning practices. Under this circumstance, BUDEM （Beijing Urban Developing Model）, which has multi-scale and multi-dimension research methods, is established. BUDEM （Phase 2） is composed of land development module （macro-level and micro-level）, spatial ＆ attribute of population synthesis module, residential location selection module, enterprise location selection module, and activitybased transportation module. These modules can be applied for simulating urban land expanding ＆ redevelopment, as well as evaluating correlated spatial policies.
