结构变化不明显。水域、居民地、耕地动态度比较大，变化较为剧烈；未利用地动态度最小，变化缓慢。1990-2002年间水域、居民地、耕地与其他土地利用/覆盖类型间相互转化面积差额较大，转入面积大于转出面积，即在相互频繁转换同时单边转入明显；林地、草地、未利用地与其他土地利用/覆盖类型间相互转化面积差额不大，处于一种动态均衡状态。

When reached logarithm growth phase, it was poured or the medium was removed. 5 mL medium containing 10 mg/L mitocin-C was added , kept at 37 ℃, and then cultured in saturated humidity warm box with the CO2 of 0.05 fraction volume for 2 or 3 hours. It was coated with 0.1% gelatin in 6-hole plate, laid for over 30 minutes, and then threw away or the medium with mitocin-C was removed, washed with phosptat buffer for 5 times so as to remove the mitocin-C. 2 mL 0.05% trypsin digestive cells were added, and it was observed under microscope. When crevice appeared, cells became round (about 2－4 minutes), digestion was stopped by adding medium of the same volume, and blew up with straws repetitively to make it into monoplast suspension. Special-used cover glass was put in the center of cell counting chamber. Cells were sucked in by glass siphon, and cell suspension flew out at bucket of up or down-sides of counting chamber, until the cover glass was filled with fluid. Living cell were inoculated at concentrations of 3×108, 5×108, 1×109 L－1 after their number counted.
