基于生态的章丘长白山小流域治理模式探析

Analysis of Ecologically-Based Improvement Model for Chang Baishan Small Watershed in Zhangqiu

摘要:

长白山小流域位于济南市东部章丘区境内,主要分为梭庄片区与万山片区,该流域内以低标准梯田、经果林、稀疏林地及荒草地为主,梯田田面不整,损毁情况较为普遍,稀疏林地面裸露,沟道淤积严重,小型水保工程不足, 整个流域治理水平较低。开展流域综合治理,以小流域为单元,以生态治理为中心,以控制水土流失和面源污染为重点,合理布局,改善生态环境,实现综合效益的最大化。

Abstract:

The Chang Baishan Small Watershed is located in Zhangqiu District, eastern Jinan. It is mainly divided into the Suozhuang Area and the Wanshan Area. The watershed is dominated by low-standard terraced fields, economic forests, sparse woodlands, and grasslands. The terraced fields are irregular and widely damaged; the sparse woodlands have exposed surfaces; the gullies are severely silted; and there is a lack of small-scale soil and water conservation projects, resulting in an overall low level of watershed management. Taking the small watershed as a united unit, the comprehensive watershed improvement should be carried out by centering on ecological improvement, focusing on controlling soil erosion and non-point source pollution, and making rational layouts to improve the ecological environment and maximize comprehensive benefits.
