This study was carried out to establish a spatial decision support system for evaluating climatic aspects of a given geographic location in complex terrains with respect to the quality apple production. Monthly climate data from S6 synoptic stations across South Korea were collected for 1971-2000. A digital elevation model (DEM) with a 10-m cell spacing was used to spatially interpolate daily maximum and minimum temperatures based on relevant topoclimatological models applied to Jangsoo county in Korea. For daily minimum temperature, a spatial interpolation scheme accommodating the potential influences of cold air accumulation and the temperature inversion was used. For daily maximum temperature estimation, a spatial interpolation model loaded with the overheating index was used. Freezing risk in January was estimated under the recurrence intervals of 30 years. Frost risk at bud-burst and blossom was also estimated. Fruit quality was evaluated for soluble solids, anthocyanin content, Hunter L and A values, and LID ratio, which were expressed as empirical functions of temperature based on long-term field observations. AU themes were prepared as ArcGlS Grids with a 10-m cell spacing. Analysis showed that 11 percent of the whole land area of Jangsoo county might be suitable for quality ‘Fuji’ apple production. A computer program (MAPLE) was written to help utilize the results in decision-making for site-selection of new orchards in this region.

정밀 수치기후도를 기반으로 고품질 사과생산에 적합한 지역을 정밀하게 탐색할 수 있는 시스템을 개발하였다. 이 시스템을 전북 장수군에 적용하여 후지 및 쓰가루 품종의 재배적지를 도출하였다. 수치기후도는 장수군 주변 7개 기상청 표준관측소로부터 얻은 1971-2000년 기간 일 최고 및 최저기온의 윌별 평균값을 토대로 지형기후모형에 의해 사방 10m 격자점의 기온자료를 공간내삽하여 얻었다. 기온자료로부터 사과의 만개기를, 4윌 최저기온으로부터 종상일을 추정하여 상해위험도를 산정하였고, 재현기간 100년의 1윌 극 최저기온으로부터 동해위험도를 산정하였다. 토지의 경사, 토성 및 토지이용도를 고려한 재배가능지역에서 기상재해 위험지역을 제외시키고, 남은 지역에 대해 품질기준을 적용하벼 최종적인 재배후보지를 도출하였다. 품질기준인 Anthocyanin 함량, Hunter A value, L/D Ratio, Fresh Firmness, Soluble Solid에 미치는 기후의 영향을 경험식에 의해 표현하고 이것을 수치기후도에 적용하여 각 품질기준별 적합지역을 탐색하였다. 최종적으로 얻은 결과에 따르면, 쓰가루의 경우 전체 면적의 20%, 후지는 11% 가 재배적지로 나타났다. 수치기후도 제작으로부터 중첩분석에 의한 재배적지 판정에 이르는 전체과정을 ArcObject 를 이용한 Visual BASIC 프로그램으로 작성하여 자동화하였고, MapObject를 이용하여 사용자가 ArcGIS 소프 트웨어 없이도 구축된 수치기후도 등 공간정보를 직접보면서 재배적지를 탐색할 수 있는 배포용 프로그램을 제작하였다.
