| 摘 要： | 我国草原面积约占国土面积的40%，但长期以来由于农牧民的过度利用，使得草地生态系统能量流动和物质循环输出输入失去平衡，造成大面积草地退化。党的十八大以来，我国草原保护修复力度不断加大，草原生态恶化的态势得到初步遏制。多年生人工混播草地建植作为畜牧业发展兼退化草地生态修复的一项重要措施，其稳定性研究对草地生态系统可持续发展和生态文明建设具有重大战略意义。本文在查阅近20年相关研究文献的基础上，首次提出人工混播草地暂稳态学说，明确暂稳态内涵及意义，完善多年生人工混播草地暂稳态维持技术体系，为我国畜牧业健康持久发展和生态修复治理提供借鉴。

| Abstract: | Grassland accounts for about 40% of the total land area in China,but the long-term excessive resource utilization by farmers and herdsmen results into large-scale grassland degradation,as output and input of grassland ecosystem in terms of energy flow and material circulation are out of balance. Since the 18th National Congress of the Communist Party of China,great efforts of grassland protection and restoration have been continuously made,and therefore the deterioration of grassland ecology has been preliminarily prevented. The construction of perennial mixed sowing artificial grassland is an important measure for animal husbandry development and ecological restoration of degraded grassland,and has great strategic significance for the sustainable development of grassland ecosystem and the construction of ecological civilization. In this paper,we reviewed the progress of the relevant researches in the recent 20 years,and put forward a theory of Quasi-stable state for the mixed sowing artificial grassland. We define the contents and significance of Quasi-stable state,and construct a technological system to maintain the Quasi-stable state in perennial mixed-sowing artificial grassland. This work provides guidance for the healthy and sustainable development of animal husbandry and ecological restoration in China. |
