This study aims at choosing indicators to measure the effect of utilizing biotop map, and analyzing its effect by an indicator from the perspective of performer. The Primary performance indicators are made through specialist survey using SMART. As a result, three indicators are chosen: “Discussion of the period of an environmental effects evaluation(reduced effect)”,“Plan and execution of environment and ecology plan in an urban development site”,“Minimizing ecological damage in an urban development.” The result in each indicator is as follows. The indicator of discussion of the period of an environmental effects evaluation(reduced effect), the average reduction rate in statistically meaningful level reduced 6.08% and 11.64% respectively in 2004-2005. In this period, environment information system was established and the reduction effect is shown in this period by reinforcing environment effect estimation using biotop map. As to the indicator of utilizing biotop map in an urban development site, the Seongnam P site case shows that biotop map was used when they set up an development plan. In case of minimizing ecological damage in an urban development, the Gwangjingu G-dong case shows that it was used to appoint preservation sit, and mediate development restrict area. Accordingly, the biotop map utilizing effect is confirmed through core performance indicators and verification of the indicators using SMART. The further research is encouraged to find evaluate indicators and verify the effect quantitatively to increase the use of biotop map.

The purpose of this study is to select the appropriate wild herbaceous plants on the rooftop. For the purpose of the experiments, 14 wild herbaceous plants were chosen. As the results of the experiments, the wild herbaceous plants growing on the culture soil(perlite) Among the 14 kinds of wild herbaceous plants, such as Chrysanthemum boreale, Taraxacum mongolicum, Aster Koraiensis, Aster yomena, Oenothera odorata, Oenothera lamarckiana, Patrinia scabiosaefolia showed good effects on growth of above ground parts. Therefore, these plants will effective for the rooftop revegetation. Callistephus chinensis and Lotus corniculatus var. Japonicus showed good height growth, wherase covering rate was worst. Chrysanthemum boreale, Platycodon grandiflorum, Patrinia scabiosaefolia were plant height, wherase covering rate was not good . For the expected number of seedings more than 3,000 per square meter, many seedings got withered to death while the survivors were suppressed to grow slow in the early stage due to the densityproblem.

The purpose of this study was attempted to establish concepts of environmental-friendly applications of flood plain and to suggest the application plans. The results of this study can be summarized as follows; 1.Roles of flood plain as biotop (restoration, preservation, and creation of stream corridor ecosystem) should be considered. 2.Application methods considering environmental and scenic values should be reviewed. 3.Application methods reflecting values as regional ecological resources should be planned. 4.Preservation and application should be considered together, and obtaining a means of living for regional residents and creation of economic profits should be considered together. 5.Land application and approach method by usages (integrated management model) should be applied to utilize and manage flood plain efficiently. 6.Flood plain application programs should be designed reflecting opinions of regional residents. 7.With respect to space planning of flood plain, introduction of facilities focused on ecosystempreservation/ecosystemrestoration/experiences/observation/learning/culture/ recreation/water purification could be reviewed positively.
