- Abstract:
-
The dump of Wulantuga coal mine in Xilin Gol Grassland was taken as the research site, the vegetation restoration effectiveness of bio-fence and sand barrier fence was evaluated by analyzing the soil properties (temperature, humidity, organic matter, and pH value) and vegetation parameters (plant species, density, and coverage). Preliminary analysis indicated that top soil temperature in the biological fence areas was 2~5℃ which was lower than in the sand barrier zone. Bio-fence could protect the plants by shading. Topsoil moisture in bio-fence areas increased by 0.6%~1% compared with the sand barrier areas. Bio-fence could help increase the humidity. Organic matter of topsoil in bio-fence areas increased by 2~5.80 g/kg compared with the sand barrier areas after 5 years of measures implementation. In the plant communities, the proportion of perennial herbaceous plant species was 13.84% more than that in the sand barrier fence zone. The average density of plant and total cover of vegetation in bio-fence areas were 2.60 m2 and 18.50% higher than those in the sand barrier areas, respectively. The effectiverness of vegetation restoration for bio-fence (with a single grid of 20 cm×20 cm) currently used in the coal mine of Xilin Gol Grassland was better than for the sand barrier (line space of 30 cm×10 cm).
