In order to extend the ecological protection model of Saihanba to the whole country, considering the regional heterogeneity, we improve the evaluation index system of problem one, constructing a three-level fuzzy comprehensive evaluation model, scoring the ecological environment status of each region, and then selecting Tianjin, Shanxi, Shandong, Ningxia and Hebei, which have lower scores, as the ecological region construction place. Finally,according to the national average level and the selected regions’ own situation, suggestions on the number and scale of construction are given,and through the carbon absorption and forest area fitting curve, the contribution of ecological area construction to China's carbon neutral target is judged.
