近代黄河三角洲土地资源的开发利用

近代黄河三角洲具有广阔的土地资源,由于盐渍化面积较大,土地垦殖指数较低,土地生态环境条件脆弱,而且土地开发利用受地表淡水资源的年际与季节分配的影响。当前土地生产力水平较低,但开发利用的潜力大,开发的紧迫感加强。开发利用黄河三角洲的主要途径有:①改造低产田,挖掘土地增产潜力;②扩大平原林地,营造林网,改善生态环境;③利用现有林场,逐步建成畜产品生产基地;④利用沿海滩涂和陆地水面发展养殖业与种植业;⑤处理好土地开发与油田建设的关系,发挥土地与油气资源两大优势;⑥运用遥感资料监测土地资源的动态变化,为及时合理地变更土地利用提供依据,以充分发挥土地资源的生产潜力。

THE EXPLOITATION AND UTILIZATION OF THE LAND RESOURCES OF THE MODERN YELLOW RIVER DELTA

The modern Yellow River delta is extremely rich in land resources. Because of larger sa-linized areas, lower index of cultivated land, fragile ecological environment, and the exploitation and utilization of the land being affected by the annual of seasonal distribution of the fresh water, the level of the present land productivity is rather low. However, despite of this, the potentiality of its exploitation and utilization is great, Such a task is increasngy pressing.For the time being, the main measures for developing the delta may be considered as follows: 1. Improve the low-yield fields and develop the productive potentiality of the land. 2. Improve the environment by expanding the forest land of the plain and establishing the windbreak belts. 3. Develop the present grazing land step by step into a productive base of livestock. 4. Utilize the seabeach and the internal water resource for breading and planting. 5. The relations between the land development and the oil-field construction must be treated correctly so as to give full play to the advantages of both land and oil. 6. In order to make necessary and timely changes about the utilization of the land according to scientific data to fully exert the proctive potential of the land resources, the remote sensing materials should be employed to monitor the dynamic changes of the land resources.
