- 摘要:
- 和田地区兼具农业区和生态脆弱区的特点，通过分析1949年至今和田地区耕地面积和单产变化过程及其相互关系，发现其耕地变化具明显阶段性，且与特定全国背景吻合，反映了受外界影响强烈。且在耕地开发的初中期曾有过大规模的以开荒弃耕为特点的极端行为，并由此产生了相应的负面结果。结论可为该区今后农业和经济的发展提供借鉴。
- Abstract:
- Through analyzes on the change process and the relationship between the cultivated land and the yield in the Hetian district since 1949,it was found that the change process has obvious stages and all the stages are related with the national background which showed being influenced intensely by out forces. And in this district, during the original and middle stages have extreme actions, which featured with large scales, ploughed and abandoned land, for these behaviors, many corresponding negative results showed.
