| 摘 要： | 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。

| Abstract: | As a new objective for global management as well as a new method of analyzing ecosystem, ecosystem health is embraced by many researchers with great concerns in the modern ecology. Agricultural ecosystem is an open artificial system and has many output and in put of energy and material. Agricultural ecosystem is different from natural ecosystem. Agricultural ecosystem is an ecosystem controlled and managed by human to satisfy the expectations with regulated system structures and altered industrial scales. The system structure exerts significant influence on the system function. A healthy agricultural ecosystem not only has good ecological environment, reasonable proportions of primary production and secondary production in the agricultural eco-economic system, but also has endurable and stable economic benefit. Agricultural ecosystem health is defined as the capability to avoid "disorder syndrome", withstand stress and meet the requirements of sustainable agricultural production. A healthy agricultural ecosystem can meet human needs without threatening natural resources or even can benefit the natural resources. The aim of healthy agricultural ecosystem is to realize high-yielding, low-input, reasonable farming methods, good stability, resilience and persistence. In this paper, based on the characteristic of agricultural ecosystem in the agricultural and pastoral zone, an index system of agricultural ecosystem assessment is formulated according to the definition of healthy agricultural ecosystem, including the factors of vigor, structure and resilience of agricultural ecosystem. The assessment model is applied to twelve counties in Chifeng region. The evaluation results indicate that the agricultural ecosystem in Hongshan County and Balinyou County is healthy, while that in Keshi-keteng County, Yuanbaoshan County, Aohan County and Songshan County can only be described as critically healthy and the agricultural ecosystems in the other six counties are not healthy. The results generated from the assessment model are basically in accordance with the actual status. Therefore, the index system and model of evaluation are proved to be credible. At last, the suggestions for the sustainable utilization of agricultural ecosystem in the agricultural and pastoral zone are put forward. Adopting the ecosystem health as assessing measure for the agricultural ecosystem can improve the management of agricultural ecosystem. |
