It needs to improve the recreational and the ecological quality of the green spaces in the city for making the city into the space where the human being and the wildlife coexist. For it, green-network should be created. So, the purpose of this study was to provide the fundamental data for constructing the landscape ecological green-network that could improve the recreational and the ecological functions of the green space in Dalsu-gu in Daegu Metropolitan Municipality. The results of this study were as follows.
1. There were 533 green spaces in Dalsu-gu. The 533 green spaces were classified 7 patterns and minutely classified into 24 types. The total area of the green spaces in Dalsu-gu was 3,329ha, especially the area of the ‘nature park’ type was turned out to be 57.49% of the total area of green spaces in Dalsu-gu, then the ‘nature park’ type was considered as a important part of the green-network in Dalsu-gu. Of the 24 types, the 9 types such as ‘nature park’, ‘river’, ‘neighborhood park’ and so on were analysed with landscape ecological indexes about recreational function and ecological function.
2. Firstly, the basic frame of the green-network in Dalsu-gu was induced by the analysis of the relationship with the area of each green space and the distance between each green space. The results was that the basic frame of the green-network in Dalsu-gu was composed of four green-network axes and its shape was turned to be cruciform(十) of northwest↔southeast direction and southwest↔northeast direction and it concentrated to Duryu-neighborhood park.
3. Secondly, zones disturbing the green-network were classified and decided their orders. As the order, zones should be changed into green space for improving the recreational and the ecological functions in city. To classify the zones disturbing the green-network, the landscape ecological indexes were applied such as 'distance among parks' and 'area of the park' for recreational function and 'ratio of the green space', 'feature of the circumference' and 'travel distance of the wildlife' for ecological function.
4. Based on the indexes of recreational function, zones were evaluated to 2 grades.
The analysis results of evaluated zones were that grade Ⅱ appeared over industrial complex and housing complex widely. The other side, grade Ⅰ appeared over housing complex. Based on the indexes of ecological function, zones were evaluated to 3 grades.
The analysis results of evaluated zones were that grade Ⅰ appeared over industrial complex and housing complex widely. The other side, grade Ⅱ and Ⅲ appeared around or between nature park and neighboring park.
5. It was necessary to consider the grade of the zones disrupting green-network and to make the zones into the green space for improving green network. Thus, the grade Ⅰ zones for the recreational and the ecological indexes were put on the basic frame of the green-network in Dalsu-gu. The result of considering the grade Ⅰ zones and the basic frame of the green-network were turned to be four basic frame of green-network, two assistance green-network and one linear blue-network.
6. To propose the plan for realizing the green-network in city, one axis(the 2nd axis) among the four green-network axes was selected as the example. The 2nd axis was considered with 'distance among parks and the results was that three sectors were turned to be insufficient for distance among parks. Case of the 1st sector, there were many schools, a public place with abundant green space, and a apartment complex reconstructed recently. In order to supplement of the park insufficiency in the 1st sector, it was desirable most to construct the children park in the apartment complex when being reconstructed.
Case of the 2nd sector, there were a vegetable garden, a empty lot and a public place with abundant green space. In order to supplement of the park insufficiency in the 2st sector, it was desirable most to construct the neighborhood park in the vegetable garden and to induce the empty lot into the green space of recreational function. Case of the 3rd sector, it was desirable most to construct neighborhood park in the green space of the model house and the children park in the housing complex when being reconstructed.
Ultimately, the purpose of this study was to induce the basic frame of green-network and to evaluate zones disturbing the green-network, based on the landscape ecological indexes. On considering both the basic frame of the green-network and the grade Ⅰ zones, the green-network that would be proper to Dalsu-gu was turned to be composed of 7 axes such as four basic green-network, two assistance green-network and one linear blue-network. But, this study was insufficiencent in regarding both wildlife and botany. And it did not become accomplished from the design which considered the quality of the sections and the detail of the green space. So it is desirable that those sides would be consequently considered with the fact that the continuous research must be accomplished.
