| As the carrier of linking cities and villages,gathering labor and population and various factor resources,town space plays an indispensable role in national economic and social development.With the deepening of territorial spatial planning and ecological civilization,the optimization of spatial pattern of towns has gradually opened a new way of thinking with ecology as the core.How to coordinate the conflict between economic development and environmental protection has become the focus of current research and the topic of concern.The natural geographical conditions of Suzhou are superior,but there are still many problems in the town space,such as land balance is broken and ecological relation is destroyed.As a means to promote the spatial ecological association of the town,the optimization of spatial pattern from the perspective of ecological network can promote the overall coordination and linkage of the whole town space,and promote the spatial integration and sustainable development.This study is based on the basis of reviewing the relevant theories and research trend and characteristics of ecological network space,and combining the era background,research domain in the process of evolution in the town of ecological network space characteristics,analyze the ecological network perspective,to analyze its and the correlation between town space and dig out the ecological network in the new requirements and new connotation in the present age,The paper constructs the spatial pattern of towns from the perspective of ecological network.On this basis,the selection of Suzhou area 51 town as the research object,can be divided into ecological network abundance abundance high class town,ecological network level classes in town and ecological network low abundance town the three categories of town,and then empirical measure of ecological network analysis,inductive conclusion of town as a result of ecological network domain spatial pattern,and summarize the optimization strategy is proposed.The results show that:(1)The spatial pattern of town from the perspective of ecological network is based on the ecological network,and it is the linkage and reorganization of town space through the multi-scale nested infiltration of the three elements of "patch-corridor-matrix" to the whole spatial elements.Patch vigor reshapes multi-node space.Corridor linkage multi-dimensional,multi-scale spatial system forms regional corridor network;Matrix shaping regional characteristic unit;With the combination of the three elements complementing each other,the spatial integration and linkage development of the town.(2)The ecological network of the whole town within the city area of Suzhou is characterized by superior ecological basis,uneven distribution of elements and low completeness and instability of the overall structure,which needs to be discussed by types.(3)From the establishment of the ecological network background as the overall optimization direction and classification of the optimization strategy.Among them,at the level of overall optimization orientation,it advocates the cultivation of multi-level ecological core,links multi-space with corridor shaping,and implements differentiated matrix conservation and utilization.On the optimization strategy level of different types of towns,the towns with high ecological network abundance level mainly build the regional characteristic pattern texture by establishing the association between towns and villages and the surrounding nature by improving the network form.At the level of ecological network abundance,the type towns promote the spatial linkage,break down the spatial barriers and improve the spatial utilization rate of the whole region by improving the degree of network.Towns with low level of ecological network abundance mainly adopt the strategy of vacating available network space,focusing on ecological restoration,to concentrate,release and restore the available ecological network space,and establish the development resilience and ecological security of towns. |
