Korea established an inventory of 1,916 sites of inland wetlands during a nationwide investigation from 2000 to 2010. If inland wetlands is included in or near various protected areas designated by the government, it can be selected as a wetland to be managed with priority. This study evaluated the aspect of management of inland wetlands by analyzing the correlation between locations of national protected areas and inland wetlands. As a result, it was shown that a considerable percentage of current inland wetland was located in areas that were designated and managed as protected areas by the government, as they had a high value of natural environment protection (527 sites, 31.61 %). When the range was widened to a radius of 1 km for protected areas, 959 sites were included and 57.53 % of sites were located in or nearby the protected areas. Among them, 46.79 % of sites were distributed up to or within a 1 km radius of waterside areas and rivers; it accounted for 81.33 % of wetlands located in protected areas. Therefore, it was found that locations of current inland wetlands were mostly in contact with rivers. The results of overlay analysis were classified into high, medium and low; the correlation of location with inland wetlands was analyzed through the analysis of separation distance of various protected areas. The number of wetlands located in areas of a 'high' value of protection was 998 (59.87 %); 289 sites (17.34 %) were distributed in areas of a 'low' value of protection. This implies that these wetlands are located in artificial areas and are more exposed to environmental pressures. Thus, these wetlands could be determined as inland wetlands, which we considered for the establishment of measures to prevent damage.

문제 정의
For wetlands exposed to higher levels of environmental pressure, special management for endangered wetlands would be needed; if damage by environmental pressures cannot be avoided, composition of alternative wetlands may be considered. Improved conservation policy is needed for the effective management of wetlands within the wetland management system of this study.
제안 방법
The number of current inland wetlands types was 25 (Mistry of Environment, 2011). As it was shown that most inland wetlands were concentrated and discovered as river types, it is necessary to enhance the investigation, discovery and conservation policy of wetlands located within mountains in future studies.
After all, analysis on wetland frequency which is distributed by individual protected area as well as by the entire protected zone makes it possible to figure out the types of protected areas where many wetlands are found. Furthermore, this study analyzed locational correlations between the protected area and inland wetlands after performing correlation analysis with the distance between the individual protected area and wetlands as s spatial variable. The types of protected areas used in this study include the followings (Fig.
The purpose of this study was to evaluate the aspect of management value of inland wetlands by analyzing the correlation between locations of protected areas and inland wetlands with subjects of 1,667 sites of national inland wetlands, excluding island areas. Areas with a high value of ecological and geographical protection were derived using fuzzy analysis and quantile regression on distance relationships with each protected area.
So far, inland wetlands have been analyzed, focusing on their discovery only based on individual valuation without considering their locational correlation with surroundings. Therefore, this study attempted to quantify the locational correlation of 1,916 national inland wetlands as of 2010 with diverse protected areas and provide basic data for selection of target wetlands which should be managed by the government prior to others. It is expected that the study results would make a contribution to the development of national wetlands conservation policies such as designation of wetland protected areas and wetland ecological corridor.

’ For spatial data needed for this analysis were used those provided by diverse services such as environmental geographic information service (EGIS) and forest geographic information service (FGIS). In addition, locational correlations between the protected areas and inland wetlands were analyzed, using ArcGIS 10.1.
The relationship between each protected area and inland wetlands were defined as variables and correlation analysis was performed (Table 2). The variable of ‘location distance between areas combining the entire protected areas and inland wetlands (X10)’ and the variable of ‘location distance between rivers area and inland wetlands (X7)’ had a coefficient of determination of 0.
성능/효과
First, it was shown that all the inland wetlands were located within 20 km of areas combining the entire protected areas. In particular, it was found that approximately 95.
Second, it was shown that areas with high, middle, and low classes of protection value accounted for 33.86%, 32.90% and 33.24%, respectively. In addition, it was shown that Baekdudaegan areas, National parks areas had high values of protection.
Third, wetlands located in areas with a high class of ecological and geographical protection accounted for 59.87% of the entire wetland area, which was equivalent to 998 sites. In contrast, wetlands located in areas with a low class of protection value were found to be relatively more exposed to development pressure.
