Since the rapid urbanization has posed a severe challenge to urban ecological security, the optimization of ecological network and the space governance are becoming a critical strategy to guarantee the ecological security of cities. Taking Wuhan city as the study area, this paper, on the basis of spatial structure pattern from source, corridor and node, examines urban ecological space and construct urban ecological network. The ecological sources were selected by the identification of connectivity and the extraction of protected areas. The ecological corridor was extracted by means of the resistance factor analysis and the accumulative consumption distance model, the ecological nodes were identified based on its resistance side. Therefore, the ecological network in Wuhan City includes 51 ecological sources, ecological corridor ( 592.82 km long) and 7 ecological nodes, the interaction of which forms the ecological network spatial structure shaped in circular parallel and branch-type radiation. On that basis, the viewpoint in space mutually united from form, connotation and its meaning was got involved to analyze urban ecological space and implement ecological space governance. The spatial boundary dividing the ecology district into core areas and buffer zones should be governed by laws and regulations as well as the governance agreements. The regular and periodically appeal channels should be constructed for the space interests. The ecological spatial relationship would be harmony by the balanced interest based on the vertically and horizontally integrated ecological compensation system to be implemented as the key point. The production and business activities should be appropriately guided by incentive policy and the urban green space should be opened for free to realize ecological space functions by expanding ecological network services.
