    摘要:

    从耕地及其周边生态系统角度出发,构建了“需求—功能—维度—要素—指标”的耕地健康产能评价框架,该框架包括耕地产能和耕地健康2个维度,以及气候条件、土壤特性、利用状况、环境胁迫状况和有益生态状况5个要素,结合研究区特点建立了耕地健康产能评价指标体系;利用国产GF-1遥感数据获取植被覆盖度、生物多样性等关键指标信息,对耕地健康产能进行客观评价;最后,选择我国松嫩平原的吉林省大安市为研究区,进行实例应用。研究结果表明,大安市耕地健康优等和健康低等占总面积的40.35%和52.07%,亚健康优等和亚健康低等比例较低,占7.58%,耕地健康状况总体良好,耕地产能较低;耕地健康产能主要受利用状况、有益生态状况影响,土壤特性影响次之。本文构建的耕地健康产能评价体系是对已有耕地质量评价方法的扩展,可为耕地合理利用与可持续发展提供科学支撑。

    Abstract:

    In order to strengthen the protection of quantity, quality and ecology of arable land, it is necessary to grasp the situation of farmland comprehensively. From the perspective of cultivated land and its surrounding ecosystem, the framework of cultivated land health productivity was constructed as “demand-function-dimension-element-index”, which included two dimensions of cultivated land productivity and cultivated land health, and five dimensions of climatic conditions, soil characteristics, utilization status, environmental stress status and beneficial ecological status. Then, according to the characteristics of the study area, the evaluation index system of cultivated land health productivity was established. At the same time, the key indicators such as vegetation coverage and biodiversity were obtained by using domestic GF-1 remote sensing data, and the healthy productivity of cultivated land was evaluated objectively. Finally, Da’an City, Jilin Province, in the Songnen Plain of China, was selected as the research area to carry out case studies. The results showed that in Da’an City, totally 40.35% and 52.07% of the total cultivated land were health-superior and health-inferior cultivated lands, respectively, while 7.58% was sub-health-superior and sub-health-inferior cultivated land. The health status of cultivated land was generally good, and the productivity of cultivated land was relatively low;the healthy productivity of cultivated land was mainly affected by the utilization and beneficial ecological conditions, and the influence of soil characteristics was the second. The evaluation system of farmland health productivity was an extension of the existing evaluation methods of cultivated land, which can provide scientific support for rational utilization and sustainable development of cultivated land.
