摘要 | The ami of this s tudy is to explore the effec ts of grassland degradat ion on soil phys ica l and chemical properties. [Meth?? od] The ratio of plant root to so il and soil tex ture on AlpineMeadow were invest igated in this s tudy, and soil availab le N, P, K, Cu, Zn, organic mat ter and pH value were also ana lyzed by routine analysis of soil nutrients in dif ferentdegraded grasslands. [Result] W ith the intensificat ion of degraded gradient and the soil depth, the ratio ofp lant root to soilwas decreased gradua lly. The highest rat io of p lant root to soilwas in 0- 10 cm depth of so il in grass land with different degraded gradients, while its ratio of plant root to soil changed from 0. 001 to 0. 040 w ith soil type of loam. Soil chem ical characterist ic changed in different degraded gradients. The content of availab le N, P, K reduced s ignificant ly w ith the soil dep th and the intens ification of degraded grad ients. The content ofCu and Zn was re lat ively lack in degraded grass land. [Conclusion] There is no significant correlat ion between nutrit ion content or pH value and the success ion degree of degraded grass land. |
