Compared with altitudes of <100m, less occupied and reclaimed useful site cropland existed at altitudes of 100�C200m. The RAD001 mTOR area of occupied and reclaimed cropland in each province was never more than 5 �� 104hm2. The area of reclaimed cropland was also no more than 5 �� 104hm2; only in Heilongjiang did the extent of reclaimed cropland exceed 10 �� 104hm2. In the 200�C800m altitude range, there was more than 10 �� 104hm2 of occupied cropland in Sichuan and Heilongjiang. At the same altitude range, there was 52.20 �� 104hm2 of reclaimed cropland in Xinjiang, which accounted for 16.52% of the total reclaimed cropland in China. Occupied and reclaimed croplands were observed at altitudes of >800m. There was about 93.08 �� 104hm2 reclaimed cropland in Xinjiang, accounting for 29.
46% from the total reclaimed cropland in China; 27.
21 �� 104hm2 reclaimed cropland was current in Inner Mongolia and 15.25 �� 104hm2 was in Gansu. The average elevation of occupied cropland was higher than the common elevation of all cropland in 6 provinces. About the contrary, 21 provinces had a decrease average elevation of reclaimed cropland than that for all cropland in each and every province. We also located the regular elevation of reclaimed croplandIfosfamide was lower than the regular elevation of occupied cropland in 15 provinces (Table five).Table 5Comparison among the typical elevation of occupied and reclaimed cropland and normal elevation of cropland in all provinces (excluding Hong Kong, Macau, and Taiwan) in China from 2000 to 2010.3.four.
Fragmentation Evaluation of Occupied and Reclaimed CroplandOnly 10 provinces, Xinjiang, Heilongjiang, Hebei, Inner Mongolia, Shandong, Qinghai, Gansu, Tibet, Guizhou, and Hainan, had fragmentation of reclaimed cropland that was less than the fragmentation of occupied cropland (Figure 5). In most other provinces, reclaimed cropland occurred in small scattered plots, but occupied cropland was fairly intact in large-scale, unfragmented pieces of land. The fragmentation of occupied cropland in descending purchase is Jilin (0.27), Guizhou (0.26), Liaoning (0.25), Hunan (0.25), Tibet (0.21), Guangxi (0.21), Sichuan (0.twenty), Gansu (0.20), Jiangxi (0.20), Heilongjiang (0.19), Hubei (0.19), Inner Mongolia (0.17), Hainan (0.17), Xinjiang (0.16), Fujian (0.16), Hebei (0.16), Chongqing (0.16), Yunnan (0.15), Shanxi (0.15), Anhui (0.14), Qinghai (0.
