Abstract  

There are two administrative modes in agricultural production in the Sangong River basin of Xinjiang: decentralized and farm-like, which result in different cropland landscapes in the basin. Investigation results showed that: (1) In the process of cropland expansion in the Sangong River basin, the growth of decentralized croplands played a dominant role from 1989 to 1999, the growth of farm-like croplands was predominant from 1999 to 2007, and the difference in agriculture irrigation technology was the key reason. (2) The difference of land use system resulted in different characteristics of cropland patches. The cropland patches in the decentralized administrative mode were characterized as small scale and high density, whereas those in the farm-like administrative mode were large scale and low density. (3) The selection of crop variety in farm-like mode was macro-controlled by the government, and that in decentralized mode was free selection, which to some extent resulted in different cropland landscape patterns. (4) The abandoned cropland landscape was also different in the two administrative modes. The area of abandoned cropland in farm-like mode was 2.49 times of that in decentralized mode. Most of the former abandoned croplands are successively distributed in the fringe of oasis and are adjacent to desert or gobi, and the later showed a dispersed pattern in spatial distribution.
