河西古浪县沙漠绿洲边缘土地合理利用对策

Rational Land Use Countermeasures in Gulang Desert Oasis in Hexi Corridor

通过对河西古浪县腾格里沙漠南缘新垦绿洲区农业生产、土地与水资源利用现状,区域种植结构、经济发展水平与生态环境建设等内容进行调查分析,结果显示:项目区农业用地资源有限,水资源短缺,农作物品种单一产业结构简单,经济作物种植面积小,严重制约了区域生态农业整体发展水平。为了改善绿洲边缘生态环境和发展新垦人工绿洲农业生产,提高区域土地利用效率,推广节水型生态农业,增加区域经济收益,采用在项目区增加种植经济植物、节水型农作物品种的种植面积,发展优质牧草和地膜种植面积,扩大养殖业等试验研究的方法和措施,调整区域产业种植结构,改革现行农田耕作技术,改善绿洲边缘生态环境,提高区域土地利用效率和增强土壤肥力,达到明显的经济效益,为沙漠绿洲边缘发展生态农业和促进区域农业可持续发展起到示范作用。

Based on the analyses for agricultural production, status of land and water resources, regionalimited agricultural land resources, water shortages, single crop species, simple industrial structure, and small crop planting area severely restricted the development of regional ecological agriculture in the project area. In order to improve the ecological environment in oasis edge, develop the new cultivated agricultural oasis, improve land use efficiency, promote water-saving eco-agriculture, and increase regional economic benefits, some countermeasures were involved. They include trying to increase the planting area of economic plants and water-saving crops, developing quality forage and film mulching planting area, and expanding aquaculture. These countermeasures improved regional industrial planting structure, existing agricultural farming technology, ecological environment in oasis edge, and land use efficiency, enhanced soil fertility and received significant economic benefits, which would play the demonstration roles in the development of ecological agriculture and regional sustainable development of agriculture in the oasis edge.
