水土流失类型区划分是实施水土保持措施的重要依据。针对潍坊滨海区的水土流失问题,在摸清水土流失现状的基础上,根据划分原则和水土流失特点,采用定性与定量相结合的方法,将潍坊滨海区水土流失区域划分为3个类型区,即南部灌区水蚀微度侵蚀区、中部建设用地水蚀轻—中度侵蚀区、北部建设用地风蚀中度侵蚀区,并将中部建设用地水蚀轻—中度侵蚀区细分为建成区、在建区和规划待建区3个亚区。对每个分区的水土流失特征进行分析与描述,提出了有针对性的水土流失防治措施。
The division of soil and water loss area is an important basis for implementing soil and water conservation measures. Aiming at the problem of soil and water loss in Weifang coastal area, based on the current situation of soil and water loss, according to the principle of division and characteristics of soil and water loss, the area of water and soil loss in Weifang coastal area is divided into three types, Namely, water erosion micro-erosion area in southern irrigation area, water erosion light-moderate erosion area in central construction land, and wind erosion medium erosion area in northern construction land, and subdivided water erosion light-moderate erosion area in central construction land into built-up area, And plan to be built area 3 sub-area. The characteristics of soil and water loss in each subarea are analyzed and described, and the targeted prevention and control measures of soil erosion are proposed.
