- Abstract:
- Based on land data derived from 2000, 2005 and 2010, the land use dynamic change of Lanzhou City in recent 10 years was systematically analyzed. By using land dynamic degree, land use degree, land use structure diversity, dominance and evenness, quantitative evaluation of changes of Lanzhou City land in the direction and speed and the evolution of land use spatial pattern were carried out. The results showed that land use structure in Lanzhou City had changed significantly from 2000 to 2010, agricultural land reduced, however, construction land and unused land increased; with respect to land-use speed and land use degree, land use in the city was still in a period of adjustment; land landscape pattern model showed that the diversity index and evenness of Lanzhou City land had reduced, but land dominance index has increased gradually; the change of land spatial pattern was closely related to economic development and cropping structure, the true reason of land use patter change of Lanzhou City was due to human activities.
