生态系统健康作为全球管理的新目标,作为分析生态系统的新方法而受到青睐,是现代生态学的研究热点之一。本文根据生态系统健康的内涵和农牧交错带农业生态系统的特点,从活力、组织结构和恢复力3个方面选取18个指标,构建了农牧交错带农业生态系统健康的评价指标体系。在此基础上建立综合评价模型,应用于赤峰12个旗(区、县),得到如下结果:农业生态系统健康状况处在“健康”标准是红山区和巴林右旗;处在“临界健康”标准是克什克腾旗、元宝山区、敖汉旗、松山区;处在“不健康”标准是宁城县、林西县、巴林左旗、喀喇沁旗、阿鲁克尔沁旗、翁牛特旗。评价结果基本上反映了当地农业生态系统的健康状况,说明建立的评价指标体系与模型是可行的。最后提出了农牧交错带农业生态系统持续利用的对策。
Ecosystem health, as a new global goal of management, is favored as a new method of analyzing ecosystems and is one of the hot topics in modern ecology. According to the connotation of ecosystem health and the characteristics of agroecosystem in the ecotone between agriculture and animal husbandry, this paper selects 18 indicators from the aspects of vitality, organizational structure and resilience, and establishes the evaluation index system of agro-ecosystem health in the ecotone between agriculture and animal husbandry. Based on this, a comprehensive evaluation model was established and applied to 12 flags (districts and counties) in Chifeng. The results were as follows: The health condition of agroecosystem was in Hongshan District and Balin Right Banner in “Health” standard; Critical health “standard is Keshiketeng Banner, Yuanbaoshan District, Aohan Banner, Songshan District; in the” unhealthy "standard is Ningcheng County, Linxi County, Bahrain left flag, Kalaqin Banner, Aru Kerqin flag, Wengniute flag. The results of the evaluation basically reflect the health condition of the local agro-ecosystem, indicating that the established evaluation index system and the model are feasible. Finally, the countermeasures of sustainable utilization of agro-ecosystem in the ecotone between agriculture and animal husbandry are put forward.
