运动公园的树木：遮荫策略与场地关系

Render the planting strategy of a sports park, with the trees doing specific jobs rather than decorating. Show three distinct conditions in one view: a formal avenue of evenly spaced deciduous trees with high clear trunks lining the walking loop, casting a continuous dappled shade band along the path; a loose cluster of broad low-canopy evergreens over the seating and picnic area, giving dense shade at ground level; and a deliberately open zone around the courts where trees are set well back beyond the fence line so no leaf litter falls on the playing surface and no shadow crosses it. Detail the ground beneath each condition differently — mown grass under the avenue, bark mulch and worn earth under the cluster, mown edge to the court zone. Show the trees at genuine maturity with proper trunk calliper and canopy spread, not nursery stock. Include tree grilles where the avenue crosses paving. Show mid-afternoon sun so the shade patterns are the subject. Photorealistic, green, structured, eye-level view.
