Based on researches on soil animals in burned forest areas and contrast sample lands around Tahe County in Heilongjiang Province during different years,we analyze the category and quantity of soil animals in order to take them as a biological indicator to reflect the environmental conditions and the restoration after fire.In October,2003,we chose six burned forest areas in different years from 1987 within the study area and a sample land which wasn't destroyed by fire.Separating soil animals by the methods of picking up,Tullgren and Baerman,we obtained 4 phyla,7 classes and 22 orders in all.In addition,soil animals in burned forest areas differ obviously during different years. (1)The category and quantity of macro-soil faunas prove to be very few,especially Enchytraeidae,which takes up a lower proportion in macro-soil faunas the first one to three years after fire,however,some macro-soil faunas which have strong moving abilities,such as centipedes,spiders etc.,account for higher proportions.Furthermore,the number of Enchytraeidae gradually increases and tends to be stable after burning three to five years. (2)Of all the meso-and micro-soil animals,Protura only appears in burned forest areas after burning 16 years and the contrast sample lands,thus,we can conclude that Protura is a fauna which can indicate stable habitat. (3)After burning,the first species which are able to invade and restore are those macro-soil animals possessing strong moving abilities,and then the meso-and micro-soil animals,which are in the prosperous period six to seven years after fire,when the category and quantity begin to decrease and tend to be stable. (4)The intensity of fire influences the restoration of soil animals community to a certain extent,that is,soil animals restore at a higher speed in the areas which suffered from mild burning,after six to seven years,toth the category and the quantity can even surpass those in regions not affected by fire. (5)However,the speed of restoration is relatively low in the moderately and seriously affected areas,which may take longer than 16 years to restore to a normal level.
