Method for constructing micro-ecosystem applied to urban hard river channel
The invention discloses a method for constructing a micro-ecosystem applied to an urban hard river channel. The method comprises the following steps that: (1) a micro-ecological device is built, a frame of the device is made of bamboo materials, a trumpet-shaped opening defined by a fishing net is formed in the top of the device, a planting groove is formed in the bottom of the device, and the periphery of the device is wrapped by a fishing net with small meshes; (2) a plant planting matrix is laid in the planting groove in a layered manner, and a common matrix filler and bottom mud in a constructed wetland are adopted as the matrix; and 3) a micro-ecological system is constructed in the micro-ecological device, specifically, submerged plants are planted on the matrix and multiple types of aquatic animals are bred in the device. The invention mainly aims at a hard river channel with three hard bare sides and a flood drainage function in a city. The river channel is large in water level fluctuation, large in flow velocity in a flood season, free of growth space of aquatic organisms and has no water ecosystems. With the method for constructing the micro-ecosystem applied to the urban hard river channel, a place can be provided for field planting and growth of submerged plants and reproduction and refuge of aquatic animals. The ultimate purpose of the invention is to construct a river channel water ecosystem and improve the self-purification capacity of a water body.
本发明公开一种应用于城市硬质河道的微生态系统构建的方法。所述的方法包括下述步骤：1)搭建微生态装置，装置的框架是由竹制材料制作而成，顶部有一个由渔网围成的喇叭状开口，底部是一个种植槽，装置外围由小网孔的渔网包覆；2)在种植槽内铺设植物种植基质，基质采用人工湿地中常见的基质填料和底泥，分层铺设；3)在微生态装置内构建微型生态系统，包括在基质上种植沉水植物，在装置内放养多类型的水生动物。本发明主要针对城市三面光且兼具排洪功能的硬质河道，该类河道水位波动大，汛期流速大，水生生物无生长空间，水生态系统丧失。本发明提出一种适用于该类河道的微生态系统构建方法及装置，可为沉水植物定植生长、水生动物繁衍避难提供场所，最终目的是构建河道水生态系统，提升水体自净能力。
