Evolvement of Temporal-Spatial Pattern of Latent Domestic Emissive ness(LDE) in Central Plains Economic Region(CPER)
以中原经济区30个地级市为单元，用熵权TOPSIS法评估潜在国内排放强度（LDE）的区域差异，并用ESDA方法分析其时空格局演变，发现居民收入和消费是主要影响因素，京广铁路东西两侧LDE呈显著二元结构。
This paper evaluates the regional diversity of LDE synthetically on the method of entropy TOPSIS with 30 provincial cities as the basic spatial unit in CPER constructing evaluation index system of LDE according to the resident income, resident consumption, traffic, communication and population, and discusses the evolvement of temporal- spatial pattern of LDE in CPER on the method of ESDA. The results show that the level of resident income and consumption is the main factor impacting spatial differentiation of LDE in CPE, the second factor is traffic, the mobile telephone plays an important role and the role of Internet services must be intensified, the purchasing power of tourism in urban residents obviously above that in rural resident, the reduction of family size is better for decision making of tourism, the LDE in each city improves continuously in CPE with the trend of convergence, there is significant difference between the east and the west of CPER as a whole,Jing Guang railway is the spatial axis which makes the spatial dualistic structure that the LDE is high in the west and low in the east of Jing Guang railway and the hotspot is in the west and the cold spot of LDE is in the east of Jing Guang railway, and this structure is very stable. And the suggestions are given about coordination of regional difference in LDE according to the above conclusions
