1. a method for long term monitoring mine of western sand grassland diversity dynamic change, comprises the steps:

  • (1) scope and the border in region to be investigated is determined;

    (2) determine quadrat number, select the layout points of sample prescription;

    (3), after the layout points of sample prescription is chosen, the size and shape of sample prescription is determined;

    (4), after sample prescription determines, lay permanent monitoring point at each sample prescription corner place, be numbered and corresponding coordinate position record, and draw drawing;

    (5) permanent monitoring point set in sample district is monitored, and record kind, the quantity of each monitoring point biology;

    (6) change of biological species, quantity in each each sample prescription of survey, thus calculate the biometric indicators in this sample district, compare the dynamic rule of this sample district vegetation diversity of different time sections.
