The categories include agriculture land, forest land, transportation land, water conservancy land, building land, public infrastructure land, recreation and leisure land, mining land, and the land for other use. 2)The calculated BAF value of Yunlin area is 0.6 which shows large proportion of green space. 3)The major landscape development strategy is increasing BAF value. This could be achieved by infrastructure development strategies of Public land and the expected BAF value would be 0.8.
