The top surface height of two adjacent low bottom box dams 2 is lower than the top height of the high bottom box dam 2 and higher than the bottom height of the high bottom box dam 2. Therefore, the submerged plants in each surrounding lake area can ensure the shallowest position and have enough water depth to ensure the normal growth in the initial maintenance period.

Submerged landscape plants with low optical path preference degrees are planted in the low region of the landscape lake 1 around the lake region 11, and submerged landscape plants with high optical path preference degrees are planted in the high region around the lake region 11. Therefore, after the landscape lake 1 is finally filled with water, the plants of all levels can be effectively ensured to obtain corresponding growth light conditions.

example 2

On the basis of embodiment 1, the embodiment discloses a construction method of the stepped landscape lake, which comprises the following steps:

S1: digging or combining natural terrains to form a slope-bottom landscape lake 1 prototype;

S2: a plurality of spaced lake bottom contour lines are selected around the lake bottom of the landscape lake 1 and tamped to form a foundation of a bottom box dam 2 around the landscape lake;

S3: tamping, building or pouring a bottom box dam 2 on the basis of the tamped bottom box dam 2, wherein the landscape lake 1 is divided into a plurality of surrounding lake areas 11 by the bottom box dams 2;

S4: submerged landscape plants 3 are planted in each surrounding lake region 11,

S5: injecting water into each surrounding lake region 11 in the lake firstly ensures that the water level in each surrounding lake region 11 reaches the initial maintenance water level which is just flush with the top surface of the lower bottom dam 2 of the surrounding lake region 11, namely stopping continuously increasing the water level of the surrounding lake region 11 until the water level of all the surrounding lake regions 11 reaches the initial maintenance water level, and immediately stopping injecting water into the lake.

S6: and when all the submerged landscape plants in the surrounding lake region reach the survival rate standard of maintenance, injecting water into the lake again until the whole body reaches the standard normal water level.

The following schemes can be selected on the specific civil engineering, planting and water injection procedures:

scheme A: after all the bottom dams 2 are built and the planting of the submerged landscape plants is finished in each surrounding lake area 11, water is injected into the lake from the outermost layer of the landscape lake 1, and the water is ensured to overflow layer by layer from the bottom dams 2 at high positions surrounding the lake area 11 to the surrounding lake area 11 at low positions.

Scheme B: after all the bottom dams 2 are built and the planting of the submerged landscape plants 3 is finished in each surrounding lake area 11, water is injected into the lake from the innermost layer of the landscape lake 1, and the water is ensured to be gradually injected from the lowest part of the lake bottom to the surrounding lake area 11 at a high part.

Scheme C: when the civil engineering work of the surrounding lake area 11 is completed and the next civil engineering work of the surrounding lake area 11 is entered, the plant planting process of the surrounding lake area 11, which is completed with the civil engineering work, is started immediately, and water is injected into the surrounding lake area 11 immediately after the planting of each plant of the surrounding lake area 11 is completed until the initial maintenance water level of the surrounding lake area 11 is reached.

on the basis of scheme B: when each surrounding lake area 11 is built, after the construction of the bottom box 2 section and the front and rear radial partition walls 4 of one box 111 is completed, plant planting can be immediately carried out on the box 111, the civil construction of the next box 111 is simultaneously carried out, the plant planting of one box 111 is completed, and water is immediately injected to the initial maintenance water level until all the box 111 surrounding the lake area 11 is completely injected with water.

The utility model discloses will increase cascaded end box dam 2 along the contour line in view lake 1's lakebed topography, every end box dam 2 designs into closed form, handle into the echelonment with waters bottom topography, every piece is around lake region 11 and all can independently impound, end box dam 2 width is in order to block the lateral thrust that the position of locating was impounded as the standard, highly use the required best depth of water of the submerged plant that the position was planted as the standard, the view lake 1 after adopting this design can adopt top-down's overflow formula to progressively impound and plant, also can impound the bottom region earlier as required and then plant the submerged plant from bottom to top or choose suitable encircleing lake region 11 or box block 111 and planting successively according to required, required manpower is nimble variable, once accumulate conventional water level and use artifical concentrated construction on a large scale in order to cooperate the lake water when planting, have very strong flexibility.

Due to the existence of the bottom box dam 2, each block of the surrounding lake region 11 and even the box dam block 111 can be an independent water area, suspended matters stirred at construction parts can not influence the water quality of other regions, the planting technology can not be used for storing all water in the water area, the planting technology has good adaptability to the regions with weak water supplement, the height of the bottom box dam 2 is controllable, submerged plants planted in the initial stage are easy to manage and have high light receiving rate, the survival rate can be rapidly improved, the inspection and the reseeding of the block plants in each region are very convenient, diving or seed throwing (the roots of the submerged plants are wrapped with soil balls and thrown into an underwater planting mode, the soil balls are easy to scatter, the plants are easy to float and have low survival rate), the water quantity of the whole water area can be gradually supplemented by means of natural rainfall when a rainy season comes in the later period, and the effects of saving resources and protecting. The bottom box dam 2 which is finally left under water can play a role in dividing different submerged species, and the dominant species are prevented from rapidly expanding to invade the species with slower growth. The bottom box dam 2 itself also has the function of underwater landscape.

The utility model discloses well step-type view lake stirs water area little, does not influence non-operation region. Shallow water level, convenient planting and convenient maintenance. The water level is shallow in the early stage, and the bottom area can also be well illuminated, so that the whole light receiving is facilitated, and the whole survival rate in the early stage is improved. The segregants can still play a role in controlling the growth range of the species at a later stage. Bioremediation, no pollution and no secondary residue. The method has the advantages of saving water, saving resources, fully utilizing meteorological resources and water resources, avoiding the bare and withered submerged plants in shallow water areas caused by the continuous decline of the water level of the water body under the special condition of drought time with difficult water supplement or rapid water infiltration, and having good adaptability to water resource scheduling.

The damage to the original terrain is small, and an underwater original ecological system is fully protected. The water storage device is particularly suitable for the reservoir reformed in the hilly terrace area, saves manpower and material resources, avoids digging and digging greatly, and avoids generating a large amount of earthwork and rockwork. The water storage mode is variable, water can be slowly stored from the bottom of the lake, water can be gradually stored from top to bottom, and the flexibility is strong.

The water supply can dissipate energy and settle layer by layer through terraced fields, and the water quality is superior to that of the traditional water storage mode without ridges. The whole body can build the landscape effect of the underwater terrace.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
