  • Existing natural resources were analyzed in regional scale in order to suggest natural park guidelines as a previous step of conservation plan. Results of both existing natural resources and land potentiality in preceding paper were combined to suggest comprehensive and qualitative method for understanding of natural land. Regional characteristics of natural park were, then, analyzed by this method, and specific planning guidelines were discussed. The existing natural resources were analyzed by the degree of location quotient, which were found by comparison of the grade of vegetation naturalness and the bio-physical land unit in preceding paper. Then, allowance of existing natural resources was identified, and importance of protection was described based on this result. The bio-physical land unit on Tokyo Province was found to be composed by smaller land units, which had a variety of relationship with grade of vegetation naturalness: from the specific(1st) to many stages(5th). This meant a characteric of each land unit. By this combined approach, the characteristics and spatial distribution of natural land were discussed in the regional scale, and characteristic of nateral park were analyzed in terms of natural location. National park were located in the land unit where both land capability and importance of portection were the 6th. Quasi national park and 1 province natural park were located in the land unit where land capability was the 6th and importance of protection were the 5th. Seven province natural parks were located in the land unites were both criteria under the 5th were mixed. based on the results of this study, the followings were suggested for specific planning guidelines in the case of Takao quasi nation park: (a) conservative land use within the limit of carrying capacity of this area by the conservation of biotic and abiotic natural resources, (b) conservation of both natural and semi-natural vegetation, (c) utilization of this area as a urban forest.

  • The purpose of this study is to introduce the case of advancement of rural zoning system in a local government of Japan. The Matzgawa county, one of the local governments in Japan, sets up a new zoning system which advanced in using rural resources. In order to develop and revitalize rural region, it is necessary to use all kinds of rural resources, including agricultural as well as non-agricultural resources comprehensively. Also, the classification of agricultural land use should be reformed. The zoning on rural land should be changed to include not only agricultural use but also non-agricultural use, so as to manage comprehensively agricultural land use and its conversions. Furthermore, the land use regulation should be applied to each zone of the agricultural land.

  • In the forthcoming 21C, the barometer of cultural lives depends on that the water demand will increase or not. On the opposite site of that, the small watersheds will influence directly on how to cover the surface of watersheds with land use, no planning developing watersheds, and the rearrangement of small rivers. Espacially as the exordinary climatic phenomena, water resources and water content of the small watersheds will be confused oil exactly not to make a plan of water resources. This study area has four small watersheds groups in Gangwon-Do Province, that is, group I five small river watersheds including Changchoncheon etc., group II fiver rivers watersheds including to Hwalsanmogicheon etc., group III five small river watersheds including Singicheon etc., group IV including to Sabulanggolcheon etc. According to the land use such as dry field(or farm), ice field, forest land, building lot arid others, in small watersheds, the amount of runoff will be impacted by precipitation. The comparison between the runoff was getting from Kajiyama Formular and calculated runoff from multi-linear regressed equations by land use percentage was performed. Its correlation which was estimated by coefficient of correlation will be accepted or not, as approched 1.00000 values. As the monthly water resources amount is estimated by multi-linear regressed equations, we make a plan to demand and supply the water quantity from small river watersheds during any return periods.

  • As one of methodological approaches for objective and systematic evaluation for rural resources, a sequential system for significance determination of resources items was formulated using AHP (Analytic Hierarchy Process) as the base technique. By the system constructed in this study, the significance values were calculated for all items of standard goal system which had been presented in the first phase- paper of research works for rural resources evaluation. The results analysed and obtained in the study are summarized as follows; 1. In case that the number of resources items for evaluation are relatively large, stepwise matrix method is considered as the better one for pair-comparison works in view of evaluator's convenience and consistency. 2. The significance valuing results for most resources items showed a considerable difference between characteristic areas, especially in aspects of land and human resources, so being considered as wet reflecting the specific areal varieties, 3. On land resources, the items for industrial development and land use showed higher significance value, while natural environment resources the items for ecological varieties and on human resources the items for artificial facilities. However, lower-valued ones were the items for mineral stocks in land resources, for control and protection in natural environment resources and for lower-level culture heritage respectively.

  • Land-use change has an important role in the hydrologic characteristics of watersheds because it alters various hydrologic components such as interception, infiltration, and evapotranspiration. For example, rapid urbanization in a watershed reduces infiltration rates and increases peak flow which lead to changes in the hydrologic responses. In this study, a physical hydrologic model the soil and water assessment tool (SWAT) was used to assess long-term continuous daily streamflow corresponding to land-use changes that occurred in the Naesungchun river watershed. For a 30-year model simulation, 3 different land-use maps of the 1990s, 2000s, and 2010s were used to identify the impacts of the land-use changes. Using SWAT-CUP (calibration and uncertainty program), an automated parameter calibration tool, 23 parameters were selected, optimized and compared with the daily streamflow data observed at the upstream, midstream and downstream locations of the watershed. The statistical indexes used for the model calibration and validation show that the model performance is improved at the downstream location of the Naesungchun river. The simulated streamflow in the mainstream considering land-use change increases up to -2 - 30 cm compared with the results simulated with the single land-use map. However, the difference was not significant in the tributaries with or without the impact of land-use change.

  • The purpose of this study was to suggest basic natural park planning guidelines which have to be considered before conservation plan. For this purpose, land potentiality was analyzed in the regional context. Natural parks in Tokyo Province were chosen as study areas because park systems in Japan and Korea are similar and lots of information are available in Japan. Land capabilities of study areas were analyzed, then the results were utilized to discuss how the natural parks. Land potentiality was analyzed by the degree of location quotient of land use allowance in homogeneous bio-physical land units, then comprehensive potentiality of bio-physical land units was revealed from existing and historical land use allowance. These 2 allowances, also, were utilized to find the limit of land use intensity, and the results were used for qualitative identification of the land potentiality and the land capability. As a results, the land use allowance and characteristics of 6 groups were identified as shown in Table 3 and Figure 6. Qualitative analysis of land potentiality in this study enabled to disscus the conservation and/or preservation of natural parks, based upon elements of land, and the guidelines of natural park conservation policy were suggested from the characteristics of land potentiality and regional relationship. This discussed land potentiality, and existing natural resources which were stressed from conservational view point need to be combined for comprhensive understanding of land resources.

  • 본 연구는 토지비축사업이 재원조성에서 LH 채권에 의존적인 현행 구조로는 사업의 지속성을 갖기 힘들기 때문에 근본적 개선방안이 필요하다는 인식에서 출발하였다. 토지은행사업의 특성상 사업초기에는 비축물량의 확보가 우선시되므로 자금투입만 집중적으로 이루어지고 회수는 장기에 걸쳐 일어난다는 점을 고려하고, 또한 토지은행 운영주체인 LH의 재무여건이 악화되어 토지은행 사업초기의 필요자금을 충분히 조달할 여력이 안된다는 점을 고려할 때, 현행 LH 적립금과 채권발행에만 의존하는 재원조달구조는 지속성에 한계가 있다. 따라서 사업초기와 정착단계에서의 특성을 감안하여 재원조달수단은 차별적으로 고려되어야 할 것이다. 사업초기에는 정부재정을 통한 지원이 불가피한데, 토지은행을 LH에 설치한 취지를 살려 직접적인 지원보다는 한시적 보증 등 간접적인 지원이 바람직할 것이다. 간접적인 재정지원방식으로는 별도의 토지은행채권을 도입하는 방안을 제시하였다. 이를 위해서는 공공토지비축법 개정을 통해 '토지은행채권 발행' 조항을 신설하되, 사업초기에는 자체적인 채권상환능력이나 담보력을 갖고 있지 못하므로 '한시적인 정부보증' 조항을 동시에 신설할 필요가 있다. 이에 부가하여, 토지은행 구분계리방식의 변경도 필요하다. LH 고유계정과는 독립적으로 토지은행계정에서 별도의 채권을 발행할 경우 토지은행계정은 LH 고유계정과 명확히 구분될 필요가 있으며, 공기업 준정부기관 회계사무규칙을 개정하여 토지은행계정을 국가재정법상의 기금에 준하여 통합재무제표 작성대상에서 제외토록 함으로써 회계처리지침 변경의 근거를 명확히 해둘 필요가 있다.
