机修梯田的埂坎多为复式埂,占地比例大。随着机修梯田的大面积推广,梯田埂坎合理利用问题逐步被提到重要议事日程。山西省的梯田埂坎主要为土质埂坎和石质埂坎两类。根据典型调查测算,全省梯田埂坎资源现状为7294万hm2,利用率为2315%。开发利用梯田埂坎资源,具有显著的经济效益和生态效益。虽然埂坎植物会造成一定的胁地,但其影响范围仅局限在1~3m内,其影响范围内的作物减产损失与埂坎植物的增值相比微不足道。大力开发利用梯田埂坎资源,不仅可缓解日益严重的人地矛盾、培育新的经济增长点,而且可加速丘陵山区的生态建设,其发展前景广阔。
Machine-made terraced ridge more than double ridge, covering a large proportion. With the large-scale promotion of the mechanical terrace, the rational use of the terrace ridge is gradually being referred to the important agenda. In Shanxi Province, terrace ridge is mainly composed of two types of soil ridge and stone ridge ridge. According to the typical survey and calculation, the present state of the terrace ridge resources in the whole province is 72.94 million hm2, with a utilization rate of 2315%. Development and utilization of terrace ridge resources, with significant economic and ecological benefits. Although plant resources can cause certain threats, the impact is limited to 1 to 3 meters. The loss of crops within the affected area is insignificant compared with the increase in plant resources. Vigorously develop and use terrace ridge resources, not only can ease the increasingly serious conflicts between man and land, cultivate new economic growth point, but also accelerate the ecological construction of hills and hills, its development prospects are broad.
