    摘要:

    從耕地及其周邊生態(tài)系統(tǒng)角度出發(fā),構建了“需求—功能—維度—要素—指標”的耕地健康產(chǎn)能評價框架,,該框架包括耕地產(chǎn)能和耕地健康2個維度,,以及氣候條件、土壤特性,、利用狀況,、環(huán)境脅迫狀況和有益生態(tài)狀況5個要素,結合研究區(qū)特點建立了耕地健康產(chǎn)能評價指標體系,;利用國產(chǎn)GF-1遙感數(shù)據(jù)獲取植被覆蓋度,、生物多樣性等關鍵指標信息,對耕地健康產(chǎn)能進行客觀評價,;最后,,選擇我國松嫩平原的吉林省大安市為研究區(qū),進行實例應用,。研究結果表明,,大安市耕地健康優(yōu)等和健康低等占總面積的40.35%和52.07%,,亞健康優(yōu)等和亞健康低等比例較低,占7.58%,,耕地健康狀況總體良好,,耕地產(chǎn)能較低;耕地健康產(chǎn)能主要受利用狀況,、有益生態(tài)狀況影響,,土壤特性影響次之。本文構建的耕地健康產(chǎn)能評價體系是對已有耕地質量評價方法的擴展,,可為耕地合理利用與可持續(xù)發(fā)展提供科學支撐,。

    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.
