Голын эргийн ой
ХӨТӨЛБӨР · ГОЛ, НУУРЫН БУФЕР
Голын эрэг, нуурын захын дагуух олон төрлийн модны бүс — усны захад бургас, дээгүүр нь улиас, хус. Үндэс нь эргийг тогтворжуулж, хөдөө аж ахуйн урсацыг саатуулж, загасны амьдрах орчныг бүрдүүлдэг.
Энэ хөтөлбөр яагаад бий болсон бэ
Mongolia's river banks lose vegetation cover to overgrazing and flood events, leading to bank erosion, sediment-loaded rivers, and loss of cold-water fish habitat. Riparian forest buffers are the single highest-impact restoration intervention per metre planted — root systems hold the bank, canopy shades the water, and the buffer filters agricultural N runoff before it reaches the river.
Хэрхэн ажилладаг
- 1
Bank survey + flood-line mapping
Identify erosion-active bank sections within 30m of the water line. Avoid sensitive spawning beds.
- 2
Two-zone planting
Zone 1 (water edge, 0-3m): willow + sea buckthorn — fibrous root mat for bank-toe stabilisation. Zone 2 (3-30m): poplar + birch — deeper canopy for shading + N filtration.
- 3
Linear spacing
1.5m along the bank, 3m between rows. Stagger species so the buffer functions even if individual trees fail.
- 4
3 жилийн арчилгаа
Y1 watering only in extreme dry years (willow tolerates a lot). Fencing protecting young trees from grazing. No herbicide.
- 5
Y3 bank position survey
GPS bank-position survey + N-filtration measurement to confirm the buffer is doing its job, not just present.

Хэмжсэн нөлөөлөл
- 100m bank planted stabilises
- ~1,500 m² riparian zone
- Agricultural N runoff filtered
- ~80% (vs. unplanted control)
- Bank erosion rate
- 5-10× slower than bare control
