Compared with altitudes of <100m, less occupied and reclaimed Ifosfamide cropland existed at altitudes of 100�C200m. The selleck chemicals llc 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% with the total reclaimed cropland in China; 27.
21 �� 104hm2 reclaimed cropland was existing in Inner Mongolia and 15.25 �� 104hm2 was in Gansu. The common elevation of occupied cropland was greater compared to the average elevation of all cropland in 6 provinces. On the contrary, 21 provinces had a reduce typical elevation of reclaimed cropland than that for all cropland in every province. We also found that the typical elevation of reclaimed croplandtelomerase was decrease than the regular elevation of occupied cropland in 15 provinces (Table five).Table 5Comparison involving the common elevation of occupied and reclaimed cropland and average elevation of cropland in all provinces (excluding Hong Kong, Macau, and Taiwan) in China from 2000 to 2010.3.four.
Fragmentation Examination of Occupied and Reclaimed CroplandOnly ten 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 many other provinces, reclaimed cropland occurred in compact 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 (0.20), Gansu (0.twenty), Jiangxi (0.twenty), Heilongjiang (0.19), Hubei (0.19), Inner Mongolia (0.17), Hainan (0.17), Xinjiang (0.16), Fujian (0.sixteen), Hebei (0.sixteen), Chongqing (0.16), Yunnan (0.15), Shanxi (0.15), Anhui (0.14), Qinghai (0.

The fragmentation of reclaimed cropland in descending order is Hunan (0.45), Fujian (0.43), Hubei (0.36), Guangxi (0.34), Beijing (0.32), Zhejiang (0.32), Shaanxi (0.30), Jiangsu (0.28), Chongqing (0.27), Jilin (0.27), Sichuan (0.26), Guangdong (0.26), Liaoning (0.26), Guizhou (0.24), Tianjin (0.23), Jiangxi (0.22), Yunnan (0.21), Shanxi (0.twenty), Shanghai (0.19), Anhui (0.16), Gansu (0.14), Inner Mongolia (0.14), Henan (0.14), Hainan (0.
