地域系统研究进展与展望

Progression and prospect on territorial system research

在述评国内外地域系统研究的基础上,分析了目前在"生态"框架下进行综合地域系统研究中存在的问题。①生态区是一个开放系统,任何尺度下的生态区都是由不同的生态系统组成,因此生态区的同质性是相对的,导致区划单元界线划定存在分歧。②受基础数据资料精度的限制,指标选取较多考虑是否能够满足数理统计需要而在一定程度上忽视了生态学上的意义和作用。③人类活动在生态区中既受到自然因子的制约,也对自然因子产生偏移,区域社会经济发展模式是自然、人文因子综合作用的结果,因而生态区包含自然因子和人文因子的信息。文中指出掌握自然—人文因子相互作用机制实现自然—人文因子的拟合是综合地域系统研究的核心,运用自然—人文因子空间化技术进行多源数据的融合是划分综合地域系统必须解决的关键技术,同时对将自然—人文空间化技术手段应用于综合地域系统划分中需要解决的问题进行了探讨。

Researches on territorial system aim at studying complex of the earth surface, revealing roles of regional differentiations and exploring regionalization at different scales, from a regional point of view. Based upon review of territorial research at home and abroad, this paper discussed some issues on comprehensive regionalization under ＂ecology＂ frame. First, ecoregion is a open system, it consists of different ecosystem at any scale, and homogeneity of ecoregion is relative term, so there is differences in boundary hnes of ecoregion. Second, restricted by precision of data, researchers put stresses on statistical needs but neglect ecological meaning to build indexes system of regionalization. Third, human activities are not only restricted by physical condition but also impact on it, so ecoregion is the results of integrated action of territorial system, and it contains information of physical and human facors. The paper point out that the interaction between physical condition and human activities is one of the most important problems of research on comprehensive territorial system. To achieve physical and human data fusion in basic unit, we must combine the data fusion techniques and regionalization methods and we should pay attention to five aspacts： classification of regional patterns, main factors in region, indexes system, model application and data fusion techniques.
