Garden distributed rainwater collection and ecological provision protection system

The invention discloses a garden distributed rainwater collection and ecological provision protection system. The system is composed of an ground tree protection part, a penetrating part and an underground rainwater collection and recovery well. Rainwater flows into the penetrating part through a large permeable cover plate, a small permeable cover plate, an outer permeable support frame and an inner permeable support frame and enters soil; when water pressure in the soil is greater than water pressure in the well, water in the soil passes through geotextile and then permeates into the rainwater collection and recovery well; when the water pressure in the well is greater than the water pressure in the soil, the water in the well permeates into the soil through the geotextile so as to supplement underground water and change the moisture content of the soil, and quick entering and slow going are realized through internal and external pressure or concentration difference. According to the garden distributed rain
