黄泛平原发展牧草产业治理风沙化土地的探讨

在分析山东省黄泛平原风沙灾害治理及防护林体系现状的基础上,指出黄泛平原风沙区防护体系单一,防护能力薄弱,近地表风沙活动强烈;黄泛平原是山东省的畜牧业发展主要区域,但其天然草地资源不足,发展潜力有限;土壤质地差、肥力低,风、沙、薄成为制约黄泛平原风沙区农牧业发展的障碍因子,但黄泛平原光热资源丰富,水分资源充足,适宜于种植牧草.基于牧草的防护能力和黄泛平原风沙区的自然资源特征,探讨了其发展牧草产业的重要性和有利条件,提出引草入田、引草入林,调整种植结构,构建以草为核心的农林牧复合生态经济系统的生产途径,并提出了发展牧草产业的几种较为典型的种植模式.

Several Considerations for Developing Grasses Industry and Controlling Wind-sand Impacted Lands in Yellow River Floodplain

Based on the analysis of wind-sand disaster control and shelter belt status of the wind-sand impacted region in Yellow River floodplain in Shandong province,it was considered that the shelter system is single and defending capacity is weak,and the wind-sand movement of surface is still strong.The Yellow River floodplain is a main region of livestock development,but the natural grassland resources are not enough,livestock development potential is not well developed,the soil quality is bad and the fertility is poor.Wind,sand and leanness become impedient factor restricting agriculture and animal husbandry development,but the light and temperature resource are abundant and the water resource is enough,the region adapt to plant grass.Accordting to the defending capability of grass and the natural resource characteristics of this region,the importance and advantage condition of developing grass industry were discussed,and the productive measures and industry development model were suggested,that is:1) to select and plant the super quality grasses for raising animals,2) to introduce grasses into farmland and forest land to establish grassland among farmland and forest land,3)to readjust planting structure to ensure an all round development,4)to establish agriculture and forest and animal husbandry comprehensive ecological and economy system focusing on grasses,at the same time,and several typical models of planting grass in process of development grasses industry in the region were provided.
