| Abstract: | Effects of grassland burning on plant height growth, moisture and chlorophyll content were studied. Burning was beneficial to height growth of most grassland plants. Burning prolonged the period of plant height growth. Community average height ralsed after burning. The height growth pme of grassland plants could be satisfactorily simulated by Logistic equation. Following burning moisture in plant became lower, only Stipa grandis was an exception. There wasn' t a reguiar pattern for the effect of burning on chlorophyll content in plant. |
