Changes of Robinia Pseudoacacia Planted Forest in the Yiqianer Nature Reserve Following the Super Storm Surge of Sept. 1992
Based on the multi-temporal Landsat TM/ETM+data acquired from 1992 to 2001, integrated with a history of robinia pseudoacacia planted forest in the Yiqianer nature reserve of Yellow River Delta, rohinia pseudoacacia planted forest changes following the super storm surge of Sept. 1992 and Aug. 1997 are analyzed. As a whole, the total area of robinia pseudoacacia planted forest continually decreased after the super storm surge of Sept. 1992 in the Yiqianer nature reserve. Before the super storm surge of Sept. 1992, the total area of robinia pseudoacacia planted forest was about 307.44hm2, but the total area decreased to about 176.85hm2 in Oct. 1993 and 110.34hm2 in Oct. 1995 after the super storm surge of Sept. 1992. Although the total area came back to about 138.69hm2 in Sept. 1996, the super storm surge of Aug. 1997 destroyed the robinia pseudoacacia planted forests again, and its total area sharply decreased to 41.31hm2 in Oct. 1997 and 34.02hm2 in May 1998 and 38.70hm2 in June 1999 and 29.70hm 2 in May 2000. Thus it can be seen that defending the robinia pseudoacacia planted forest against super storm surge is very important for forest ecosystem health.
