【摘要】 人类活动造成的用地类型变更影响区域生境质量。采用InVEST模型对河南省前坪水库建设前后库区生境质量进行评估，并结合CA-Markov模型对研究区2025年、2035年生境质量状况进行模拟和预测。结果表明：耕地、林地、草地为前坪水库库区主要用地类型，占比为90%左右；2000—2020年耕地面积萎缩，水域20 a内涨幅高达116.94%;研究区生境质量平均值由2000年的0.550 595增大为2015年的0.557 727,但在2020年下降为0.556 880,表明前坪水库建设前库区生境质量整体呈上升趋势，建设后生境质量下降；2020—2035年研究区土地利用和生境质量演变趋势与2000—2020年的基本一致，耕地削减速率减小，建设用地扩张速率明显减缓，生境质量整体仍呈略微下降趋势。更多还原

【Abstract】 The change of land use type caused by human construction activities affects the quality of regional habitat. In this study, InVEST model was used to evaluate the habitat quality of Qianping Reservoir in Henan Province, and CA-Markov model was used to simulate and predict the habitat quality in 2025 and 2035. The results show that cultivated land, forest land and grassland are the main land types in the reservoir area, accounting for about 90%. From 2000 to 2020 the arable land has been shrunk and the water area is increased by 116.94% within 20 years. The average value of habitat quality in the study area is increased from 0.550 595 in 2000 to 0.557 727 in 2015, but decreased to 0.556 880 in 2020, indicating that the habitat quality of the reservoir is on the whole increasing before the construction of the reservoir, but is decreased after the construction. The evolution trend of land use and habitat quality in the study area from 2020 to 2035 is basically consistent with that from 2000 to 2020. The reduction rate of cultivated land is decreased, the expansion rate of construction land slows down significantly and the habitat quality is still in a slightly decreasing trend on the whole.更多还原
