Problems solved by technology

Similarly, many challenges are also faced in the process of ecological restoration of wetlands. For example, when carrying out ecological restoration of flooded wetlands, frequent changes in water levels, monotonous terrain, single species, strong wind and waves, and invasion of alien species make the ecological restoration effect poor.

Embodiment Construction

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] Refer to the attached Figure 1-3 A flooded wetland "tan-beach-island" ecological restoration model is shown, and the specific restoration steps are as follows:

[0033]Step 1: Construct the restoration area: use the existing terrain, and use the beach island, high beach and deep pool as the basis to enclose the restoration area into a square structure; the center of the deep pool is located inside the square structure, and the beach island is located in the square At the inner corn...

Abstract

The invention discloses a flooding wetland 'pool-beach-island' ecological restoration mode, and particularly relates to the technical field of ecological restoration. Continuous vegetation living environments with different water depths are constructed; when the water level rises or falls again, retained species can recover quickly, and the biological succession presents a periodic rhythm under the combined action of the water level and seasons; and an elastic linkage type multi-layer ground net is laid on the terrace, the stability of a transformed terrain can be effectively enhanced, water and soil loss is avoided, the safety of the restored terrain is guaranteed, and thus the ecological restoration effect is guaranteed. On the basis of terrain design, as few and effective engineering measures as possible are carried out, rich and retainable living environment heterogeneity is constructed, technical means such as wave dissipation and alien invasive species inhibition are supplemented, and effective ecological restoration of the flooding wetland is achieved on the basis that original background conditions are reserved as much as possible.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, more specifically, the invention relates to a flooded wetland "tan-beach-island" ecological restoration mode. Background technique [0002] Flooded wetlands refer to flat areas on both sides of rivers that are inundated by river water, including floodplains, flooded river valleys, and seasonally flooded grasslands. In the wet season, it consists of flooded riverbanks, river islands, river valleys, seasonally flooded grasslands, and inland deltas that maintain perennial or seasonal water infiltration. Flooded wetlands are located in the transition zone between terrestrial ecosystems and aquatic ecosystems. Their seasonal dryness and wetness alternately create extremely high living environment heterogeneity and biodiversity. Wetlands cover only 6% of the earth's surface. However, it provides a living environment for 20% of the known species on the earth, and has an irreplaceable eco...
