Abstract

The invention discloses an onshore buffer zone. The onshore buffer zone comprises vegetation slope protection zones including a first-stage vegetation slope protection zone, a second-stage vegetationslope protection zone...an Nth-stage vegetation slope protection zone, wherein N is a positive integer not smaller than 2, and an inter-gravel contact oxidation zone is arranged between every two adjacent vegetation slope protection zones; plants are planted on the vegetation slope protection zones; each inter-gravel contact oxidation zone comprises a filtration layer made of gravel, a purification layer made of volcanic rock and an adsorption layer made of coal cinder in the water flow direction; ecological corridors are arranged in the inter-gravel contact oxidation zones; adjacent inter-gravel contact oxidation zones are arranged in a staggered manner. A vegetation slope protection-inter-gravel contact oxidation zone-vegetation slope protection type construction mode is adopted, and thepollution absorption and water purification effects are improved through multi-stage structure arrangement.

Description

technical field

[0001] The invention relates to the technical field of water body purification and pollution control, in particular to a coastal buffer zone. Background technique

[0002] Coastal buffer zone refers to the space area constructed along the banks of rivers, lakes, streams, valleys and other water bodies, which is constructed by measures such as engineering construction, vegetation planting and ecological construction. Its main functions include water and soil conservation, biological conservation, pollution control, etc. .

[0003] The construction of vegetation belts with different widths is the main research and application direction of water shore buffer zone in recent years. Existing studies have shown that vegetation belts can intercept rainwater and prevent rainwater splash erosion; reduce surface runoff and prevent surface water erosion; prevent trampling; increase water infiltration; roots fix soil and support; purify water quality and reduce non-point...

Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0028] Referring to the accompanying drawings, a coastal buffer zone includes: a vegetation slope protection belt, which includes the first-level vegetation protection belt, the second-level vegetation slope protection belt... to the Nth level Vegetation slope protection belt, where N is a positive integer not less than 2. The specific value of N is selected according to actual needs, so that the coastal buffer zone includes multi-level vegetation slope protection belt. Such as figure 1 As shown, N=3, the vegetation slope protection belt includes the first-level vegetation slope protection belt 1 , the second-level vegetation slope protection be...
