(2) Table 6: the third column header of the original table—“Water-Source Conservation Functional Area”—was wrong. The original table was as follows:
Table 6.
The type of land conversion in NKEFA in 2000–2010.
Table 6.
The type of land conversion in NKEFA in 2000–2010.
| Type | Water-Source Conservation Functional Area | Water-Source Conservation Functional Area | Windbreak and Sand Fixation Functional Area | Biodiversity Maintenance Functional Area |
|---|---|---|---|---|
| 1 | GN | GQD, HTGY, SX | YS | CD, QB, WLS |
| 2 | ZDN, ZXB | |||
| 3 | XAL, REG, CBS, SJY | DBS | HLBR, HSDK, KEQ | HND, NL, SJPY |
| 4 | QLS | AEJ | ||
| 5 | AET | TLM |
The correct header is “Soil and Water Conservation Functional Area”, as shown in the corrected table:
Table 6.
The type of land conversion in NKEFAs in 2000–2010.
Table 6.
The type of land conversion in NKEFAs in 2000–2010.
| Type | Water-Source Conservation Functional Area | Soil and Water Conservation Functional Area | Windbreak and Sand Fixation Functional Area | Biodiversity Maintenance Functional Area |
|---|---|---|---|---|
| 1 | GN | GQD, HTGY, SX | YS | CD, QB, WLS |
| 2 | ZDN, ZXB | |||
| 3 | XAL, REG, CBS, SJY | DBS | HLBR, HSDK, KEQ | HND, NL, SJPY |
| 4 | QLS | AEJ | ||
| 5 | AET | TLM |
(3) Figure 4: The legend defining the colors used to indicate biomass density was reversed in the original manuscript:
Figure 4.
Spatial distribution of biomass of NKEFAs in 2000, 2010.
Figure 4.
Spatial distribution of biomass of NKEFAs in 2000, 2010.

This should be replaced with:
Figure 4.
Spatial distribution of biomass of NKEFAs in 2000, 2010.
Figure 4.
Spatial distribution of biomass of NKEFAs in 2000, 2010.

(4) Figure 5: The unit of biomass density was originally g·m−2 and the unit of fractional vegetation coverage was %:
Figure 5.
Biomass density, total biomass, FVC of NKEFAs in 2000, 2010.
Figure 5.
Biomass density, total biomass, FVC of NKEFAs in 2000, 2010.

The unit of biomass density should be replaced with kg·m−2 and the unit of fractional vegetation coverage should be omitted:
Figure 5.
Biomass density, total biomass, FVC of NKEFAs in 2000, 2010.
Figure 5.
Biomass density, total biomass, FVC of NKEFAs in 2000, 2010.

(5) Section 3.2. (Ecological Environment Quality Change Trends): The unit of total biomass was formatted incorrectly as: Pg (1 Pg = 1015 g). This should be replaced with Pg (1 Pg = 1015 g) in the fourth line of the second paragraph in Section 3.2. (Ecological Environment Quality Change Trends).
The authors would like to apologize for any inconvenience caused to readers by these changes. The manuscript will be updated and the original will remain online on the article’s webpage.
