#### 3.2.2 Ecological Sensitivity Analysis of Various Land Resources  
By overlaying the results of the comprehensive ecological sensitivity evaluation with the land resource types, we can obtain the ecological sensitivity evaluation results for each land resource type, as shown in Table 8 and Figure 7.  
By analyzing Table 8 and Figure 7, we can obtain the following results. (1) The cultivated land is mainly moderately sensitive (nearly 3/4), followed by slightly sensitive areas (about 1/4) which are mainly located in areas far from construction land and roads. In addition, the proportion of highly sensitive areas is very small (0.24%). (2) Woodland is the dominant land type in the Tumen River Basin, accounting for 84.40% of the total basin area. The proportion of slightly sensitive and moderately sensitive woodland areas is close, with the slightly sensitive areas being more remote; the proportion of woodland in highly sensitive areas is very small (0.13%). (3) The total area of grassland is not large, and its

distribution is relatively scattered, mainly in the moderately sensitive area, followed by the highly sensitive area and the slightly sensitive area. (4) The majority of the construction land is moderately sensitive (96.59%), while the proportion of lightly sensitive areas and highly sensitive areas is small. (5) The bare land is mainly distributed in the moderately sensitive areas on both sides of the river, while the slightly sensitive areas (19.91%) and highly sensitive areas (1.31%) are scattered. (6) There are no slightly sensitive areas in the water bodies, and highly sensitive areas are larger, accounting for 45.6% of the total area of highly sensitive areas in the basin (60.97 km\({}^{2}\)). (7) Wetland area is very small, most located in the downstream of the Tumen River, and all of them are moderately sensitive areas. (8) In the areas of each sensitive level, the proportion of woodland in slightly sensitive areas and moderately sensitive areas is particularly significant, and the water body is more obvious in highly sensitive areas.
