An Initial Survey on the Construction of Ecological Energy Level Based County Green Space and Eco-Network LIU Bin-yi WEI Li-ya Abstract: With the county land use dei nition and characteristics of green space as the research background, the network structure mechanism to realize ecological energy flow, radiation and exchange was analyzed. The concept and the theory of Ecological Energy Level were put forward, and the characteristics and evolution of space and time of county green space and the other county land use for urban and rural development were analyzed. Effect analysis and evaluation research of ecological level of space was carried out. The constructive elements of ecological green space were divided into three levels of positive energy, zero energy and negative energy level and seven ranking. The method and principle for spatial connection, infiltration and isolation of green space ecological network factors were proposed based on spatial effect features of different ecological levels. Three networks were constructed: the habitat corridor network with connection as the core, the scenic greenway network with radiation as the core and the safety protection network with loading as the core. All these three networks would be ove
