1.The practice of eco-agriculture has brought about striking improvements in the agricultural ecological environment — barren hills greened, forest acreage greatly raised, soil erosion controlled to some extent.
2.The practice of eco-agriculture has brought about striking improvements in the agricultural ecological environment -- barren hills greened, forest acreage greatly raised, soil erosion controlled to some extent, organic matter content of the soil increased, and the ability of the agricultural ecological system to ward off natural disasters improved.
3.Monitoring of the ecological environment in comprehensive agricultural development in the “three rivers” area in the past 10 years indicates that, due to an organic combination of biological and engineering measures, both the types and rate of land utilization and the acreage of man-made vegetation in the area have increased markedly. Desertification and soil erosion have been effectively checked, and the comprehensive index of the eco-environment quality has been raised by one to three grades.
