Abstract:: Based on TM imagery, topographic maps and field investigation, the habitat pattern of red-crowned cranes in the Modern Yellow River Delta was analyzed with RS and GIS. Spatial diversity index (S_d) was applied to describe the temporal and spatial variation between 1986 and 2001 in the process. According to the relativity between the Red-crowned Crane habitat and spatial diversity index, we divided S_d into four categories as follows: low value (0, 0.25], mid-low value (0.25, 0.50], mid-high value (0.50, 0.65] and high value (0.65, 1.00]. A higher value indicates better habitat quality and suitability. The results showed that the fragmentation of the Red-crowned Crane habitat increased while the connectivity and suitability of the habitat decreased with time between 1986 and 2001 in the Yellow River Delta. The area of unsuitable habitat (S_d≤0.5) gradually enlarged, which accounted for 65.11%, 70.79% and 77.06% in 1986, 1996 and 2001 respectively. The area with high or mid-high S_d values (S_d>0.5), which occupied 34.9% (1986), 28.2% (1996) and 22.93% (2001), showed an obvious decreasing trend.
