公式
## How to Plan Reforestation Reforestation restores forest cover to sequester carbon and rebuild ecosystems. ### Formula **Trees Needed = Area * Planting Density** **Cost = Trees * Cost per Tree** ### Planting Density - Dense restoration: 1,000-1,600 trees/ha - Moderate: 600-1,000 trees/ha - Agroforestry: 200-400 trees/ha A new forest can sequester 5-10 metric tons CO2/ha/year once established.
计算示例
Reforest 50 hectares at 1,100 trees/ha, $2.50/tree, over 20 years.
- 01Total trees: 50 * 1,100 = 55,000 trees
- 02Cost: 55,000 * $2.50 = $137,500
- 03Annual sequestration: 50 * 5 = 250 metric tons CO2/year
- 04Total carbon: 250 * 20 = 5,000 metric tons CO2
- 05Cost per ton: $137,500 / 5,000 = $27.50/ton
常见问题
How many trees should be planted per hectare?
Restoration planting typically uses 1,000-1,600 trees per hectare. Natural thinning over time reduces this to 200-500 mature trees per hectare in a healthy forest.
How long until a reforested area captures significant carbon?
Young forests absorb carbon slowly for 5-10 years, then accelerate. Maximum annual sequestration occurs around 20-50 years. It takes 50-100+ years to approach old-growth carbon stocks.
What species should be planted?
Native species mixed plantings are most resilient and biodiverse. Avoid monoculture plantations. Include fast growers for early canopy and slow growers for long-term forest structure.
