The multi-scale and multi-level characteristics of urban-heat islands have been paid more attention in the fields of Geographic Information System (GIS) and Remote Sensing (RS) etc. Although the urban habit society can be disturbed by some artificial heat sources, it still exhibits a certain periodicity and regularity. By fully utilizing the methodology used in the study of urban heat-island effect, a concept of the eco-organic life in a urban habit society is proposed and the heat diseases based on material and energy exchange of the open and complex eco-system are summarized and analyzed. The heat and green effect and its physical generation process in an urban habit society are analyzed from the perspective of living comfort. By using a small infrared scale to detect the heat environment in an urban habit society, the features of three-dimension, multi-level, multi-object and non-linearity are highlighted. To improve the heat environment in an urban habit society, the heat environment distribution and ecology controlled by the green function are evaluated. The result shows that the construction of an urban habit society has a direct relationship with the geographic distribution of a heat environment. The green control methodology is an important operable technique. Therefore, the related innovative research and its effectiveness will be further studied in future qualitative description, quantitative simulation and measurement.
