本文通过研究分析短花针茅草原植物群落地上净生产量、生长季节地上平均生产量与多年降水量和气温的相互关系,指出短花针茅草原近年气温有逐步升高的趋势,降水量的波动成随机性。初级生产力与4—8月的累积降水量有显著的直线回归关系,而与年平均气温、≥50C的年积温没有明显相关关系。

在内蒙古包头市达茂联合旗哈雅教学牧场,采用随机区组法对短花针茅草原在不同刈割时期、次数和高度下的生物量形成规律进行了研究,旨在探索短花针茅草原的合理利用方式,为草原放牧畜牧业生产实践提供理论依据。研究结果表明,短花针茅草原对刈割高度较为敏感,适宜的刈割高度为2cm;短花针茅草原植物生长缓慢,再生能力差,不宜于频繁利用,一年适宜利用1-2次;考虑牧草产量和营养物质含量,一年两次利用的间隔期应为2-3个月;一年一次利用的最佳利用期为8月中旬以后。

Grazing management, forage planting trials and livestock yard feeding were conducted in the desert steppe on during 1984-2001. Grazing experiments with sheep using four stocking rates and two grazing systems were carried out in Stipa breviflora desert steppe of the Inner Mongolia Plateau during 1984-1990. Seven forage varieties: Agropyron mongolicum, Psathyrostachys juncea, Agropyron cristatum, Elymus cylindricus

【期刊论文】The valuation of service of recreation function of Dalinor National Natural Reserve1

Valuation of natural resources is the theoretical basis for the monitoring of the conservation and sustainable utilization of them. Travel cost valuation method (TCM) is used in this paper to estimate the value of service of recreation function of Dalinor National Natural Reserve (DNNR) of Inner Mongolia Autonomous Region (IMAR), which is located in Chifeng City of IMAR. It is estimated that the total value of the service of recreation function of DNNR is RMB 75,170,000. This result can be of some reference to both policy-making and compensating of natural resources of DNNR.
