摘要:

以半湿润半干旱的松嫩平原为例,利用InVEST模型对松嫩平原生境质量进行评估,同时,分析了松嫩平原土地利用变化对生境质量的影响。研究结果表明:1995—2015年,松嫩平原耕地和未利用地面积增长,其他用地面积减少,另外,草地、建设用地和未利用地向其他地类的转变剧烈;1995—2015年,耕地是松嫩平原的优势景观,景观破碎化程度升高;松嫩平原生境质量整体在0.6以下,大部分地区生境质量处于中、低等级,东部生境质量处于良、优等级,生境质量优于松嫩平原其他地区。对策建议:需优化耕地、未利用地和建设用地等景观格局,此外,经济增长必须与生境质量提升同步。

关键词: InVEST模型, 生境质量, 土地利用, 景观指数

Abstract:

Taking the semi-humid and semi-arid Songnen Plain as an example, we utilized the InVEST model to evaluate habitat quality and analyzed the impact of land use change on habitat quality. The results showed that: from 1995 to 2015, the area of cultivated land and unexploited land increased, and the area of other kinds of land decreased in the Songnen Plain. In addition, the grassland, construction land and unexploited land were transferred into other kinds of land dramatically. During the 21 years, cultivated land was the dominant landscape in the Songnen Plain and the fragmentation degree of the landscape increased. The habitat quality index was below 0.6 and the habitat quality in most areas was at the middle and low level, however, the habitat quality of the eastern region in the Songnen Plain was at a good and excellent level, and was better than that of other areas. Countermeasures are put forward as improving the landscape pattern such as cultivated land, unused land and construction land, and synchronizing the economic development with the enhancement of habitat quality.

Key words: InVEST model, habitat quality, land use, landscape index
