Growth effects and adaptabilities of different vegetation restoration measures of degraded meadow in Wugong mountain
By the treatments of sowed with different grass seeds,covered with different auxiliary materials,turf transplantation and enclosure in the degradation meadow areas of Wugong mountain,to analyze the growth effects and adaptability characteristics of different measures,to find the suitable methods of vegetation restoration in this regions,to provide theoretical guidance for the ecological restoration of degraded meadow and the planning and sustainable development of subtropical mountain meadows.The results showed that:(1) without auxiliary material to sow the seed ofMiscanthussinensis Anderss.had the highest germination rate and the best adaptability to the environment,vegetation coverage was 45.67％,followed by Cynodon dactylon (Linn.) Pers.,vegetation coverage was 15.33％,there were inferior growth effects of the Festucaelata Keng ex E.Alexeev,Lolium perenne L.and Eragrostispilosa (L.) Beauv.,vegetation coverage was 6％,5.33％ and 2.67％.(2) Which had the better growth effect covered with non-woven fabrics as an auxiliary measure after had sowed with grass seeds than the treatments of covered with straw curtain and non-mulching measures.(3) Which had the best growth effect of turf transplantation among all the treatments,and the native turf of Miscanthussinensis Anderss.(vegetation coverage was 93.33％,the plant height was 36.88 cm),Carexchinensis Retz.(vegetation coverage was 95％,the plant height was 49.53 cm),and Fimbristyliswukungshanensis Tang et Wang (vegetation coverage was 94％,the plant height was 41.26 cm) had better adaptability than Cynodon dactylon(Linn.) Pers.(vegetation coverage was 80.67％,the plant height was 4.29 cm).(4) In the premise of not cause significant damage to the original vegetation environment,recommended the measure of turf transplantation to repair the degraded meadow areas,recommended using the Miscanthussinensis Anderss.as the main seed,Cynodon dactylon(Linn.) Pers.as auxiliary seed,and collocation covered with non-woven fabrics when carry out the vegetation restoration works.
