一、北方平原地区城市水土保持现状城市水土保持方案编制中普遍存在重视土壤的保持而轻视对水的保持现象,表现在水保方案对土壤流失的防治措施越来越到位,但对水的长久保持措施重视不够。对土壤的防护措施有围挡、遮盖、表土剥离以备植树种草等,这些措施在北方平原地区已经基本能够满足保土的需要。对水的保持主要有植树种草增加绿化率、使用透水砖等硬化路面增加雨水下渗,这些保水措施理论上比较有效,但在实 First, the status of urban soil and water conservation in the northern plains Urban water and soil conservation programs in the preparation of the widespread emphasis on maintaining the soil while ignoring the phenomenon of water retention, manifested in the soil and water conservation program on soil erosion control measures more and more in place, but the long-term water Not enough attention to maintaining measures. Protective measures for the soil are fenced, covered, topsoil stripped for the preparation of trees and grass, these measures in the northern plains have been able to meet the basic needs of the soil. Maintain the water to maintain afforestation grass planting greening rate, the use of permeable bricks and other hardened pavement to increase infiltration of rainwater, these water conservation measures in theory more effective, but in fact
