With the rapid develop of social economic, the energy source exploitation pace also accelerated, the exploitation induced environment questions also draw many attentions from all society, protect ecology environment, adjust economic development has become the key problem about the sustainable in the world. From the field survey, the article use 3S technology and landscape structure software FRAGSTATS, analyzed the Daqing Changyuan middle northern region first, second, third and sixth oil extraction factory's vegetation landscape structure, the result shows that:1. The historic exist main vegetation types were grassland, meadow, and wetland, the vegetation type which composites by arbor and shrub and exiguity and the types singleness.2. Because of the long term oil reconnoiter and exploitation, the vegetation destroys seriously: sheep meadow, wetland, and alkali patch degradation seriously, the population in different types shows shortness and degradation in different degree, the vegetation succession were sheep meadow population→sheep meadow and one year live weed→one year live weed→bareness alkali patch converse succession, and shows seriously degradation.3. The patch density was high in the region and the areas were small. Landscape boundary index high, man made architecture and road Segmentation on landscape was high, because of the early exploitation oil extraction first, second factory landscape destroy degree higher than third, sixth factory. The result shows that in this region originally meadow, wet land landscape has suffered serious disturb and generally lose.4. Aim at these destroy situation in this region bring forward restoration measures: the de generated sheep meadow should adopt nature enclosure breed method, on the meadow wetland prevent contamination from flow into water, through transplant, refine water restore vegetation community, the restoration on alkali patch can through nature enclosure breed, and also can through small area loosen the land, choose anti-alkaline vegetation facilitate artificial restoration.
