To set up spatial index for rural landscape in Korea, we set firstly up basic scale of landscape by "Dong" or "Ri" and then analyzed land use status and topographic conditions for 117 "Ri"s in rural area using GIS application. Unit areas surveyed averaged 438.0ha with a range of 64 to 1,944 ha. According to land use, we categorized forest and water system into natural landscape, paddy, upland and orchard into agricultural landscape, and residential section, industrial facilities, and animal shed into urban landscape, respectively. According to the relative ratio in same landscape scale, we classified them into six first-landscape patterns (Fig.1, Table.1). For the first-landscape pattern, we classified the ratio of agricultural landscape into less than 30%, 30 to 70% and more than 70%, and the ratio of urban landscape into less- and more than 10 % by them.

In the group 1, where the ratio of agriculture was less than 30 %, the ratio of upland including orchard was larger than paddy and that of forest among natural landscape was 93.8%. In group 2, paddy was slightly larger than upland, especially irrigated paddy was twice as large as partially irrigated in ratio. The ratio between paddy and upland, and the relative ratio of forest was similar to group 1. The ratio of industrial and animal shed facilities in urban landscape was 19.7%, relatively larger than other groups. In the group 3, the ratio of paddy and upland in agricultural landscape was 74.7%, and that of forest was relatively smaller than group 1 and 2. The ratio of residential sections in urban landscape was smallest. In the group 4 and 5, the ratio of paddy was more than 85% and that of forest reduced. In particular, the ratio of irrigated paddy was very large more than 75%.

According to the relative ratio by slope with group, there were lots of E and F slope in the group 1, and in case of group 2 and 3, all grades of slope were even distributed relatively. Only in case of group 3, lower slope was distributed. In case of group 4 and 5, we could find similar slope distribution ratio and ratio of A slope was largest.

As a result of making an investigation of topographical distribution, there were overwhelmingly lots of highland in the group 1. In the group 2 and 3, the ratio of highland, alluvial fan or valley plain to low hill was evenly distributed and that of inland flat was large. In case of group 4 and 5, the ratio of coastal plain was largest and inland plain was the next.

Through these analyses, we could classify the agricultural landscape in Korea into six groups and understand their properties. Nevertheless, much more data should be supplemented for the national representative value.
