Description
Technical field
The invention belongs to salt-soda soil water resource process fields, more particularly, to a kind of saline and alkaline region above and below ground joint water money
Source, which is regulated and stored, utilizes system.
Background technique
Rainwater is a kind of freshwater resources being of great rarity, and especially for beach saline land, this serious water shortage region is received
For collection with using rainwater, that is even more precious.Salt-soda soil is because of water shortage, and salt concentration has exceeded the receiving energy of plant in soil
Power forms salt damage.Salt comes with water, and salt is gone with water, so must assure that sufficient freshwater resources supply, saline and alkaline land resource
It can just accomplish sustainable use.
China's coastal saline-alkali soil gross area is up to 500 × 104hm2,.It is saline and alkaline in these years with economy and industrial expansion
Area has become the fresh position of economic development, and in order to meet the needs of Development control area, " aggregate chips drenching layer " adds " hidden pipe salt discharge " to control
The method in reason salt-soda soil is widely used.The method that " the aggregate chips drenching layer " adds " hidden pipe salt discharge " to administer salt-soda soil is will be saline and alkaline
The soil improvement on ground is good or after replacing with planting soil, aggregate chips is laid below planting soil, saline-alkali soil is isolated, prevent hair with high salt
Thin water enters good soil, then weeper drain is arranged under aggregate chips layer, and capillary haline water that infiltration comes up and good soil are arranged
Water is discharged in city planting ductwork in time.It is more than simultaneously drenching layer to prevent groundwater level, causes drenching layer to fail, greenery patches elevation is used
The earthwork is padded, generally padded to be at least higher than 1.5 meters of level of ground water peak or more, realizes further away from underground haline water,
The influence of capillary water with high salt is reduced, to guarantee to change good soil no longer by salination, can normally be afforested, plant is each
Kind plant.But the method defect that existing " aggregate chips drenching layer " adds " hidden pipe salt discharge " to administer salt-soda soil is: the rain after rainfall
After water penetration enters soil, lost through aggregate chips layer into saline and alkaline laminar flow, or be directly discharged into municipal drainage pipe network, rainwater cannot be effective
Utilization, while apply fertilizer during, the nutriments such as a large amount of N P and K have also been discharged into municipal rain system therewith, also cause
The eutrophication of downstream water；Have little time the rainwash rainwater of lower infiltration when rainfall, flow into the low gesture regions such as peripheral path, increases
Add road drainage pressure and waterlogging risk, while greenery patches soil washes away road surface with runoff, stays the runoffs such as mud after causing road rain
Pollution problem；It is big to afforest earth volume, it is uneconomical.
Summary of the invention
It regulates and stores the technical problem to be solved in the present invention is to provide a kind of saline and alkaline region above and below ground joint water resource and utilizes system
System；The system is pooled to rainwater in concave herbaceous field after highly effective can collecting rainfall, and not will lead to saline-alkali soil layer and return
Salt is to planting soil layer；It is also possible to make the reduction of saline land greening absolute altitude, earth volume is reduced, while reducing to road
The runoff pollution of equal peripheral facilities.
