摘要
云贵高原岩溶地质条件导致当地的石漠化严重、生态环境脆弱,对该地区的生态系统服务功能进行评价有助于改善生态环境问题.基于InVEST模型和PLUS模型定量评估了云贵高原 2000-2030 年的碳储量和生境质量,结合自然资源区划,分析该地区2000-2030 年碳储量和生境质量的时空变化特征及驱动因子.结果表明:2000-2030 年云贵高原碳储量均值为7.323×109 t,多年呈现下降趋势,共减少 0.471×109 t,空间上呈西部高、东部低的特征,最高的四级区划是丽江市东部楚雄北部小区;碳储量贡献率最高的地类是林地(>60%),其次是耕地(>28%);碳储量空间分异解释力最强的因子是高程,交互作用最强的因子是土地利用和坡向.2000-2030 年云贵高原生境质量均值为 0.755,多年呈下降趋势,共减少 0.016,空间上呈现西部高、中部和东部低的特征,最高的四级区划是丽江市西部—怒江傈僳族自治州东南部小区;林地的生境质量最高,指数为 0.83.研究结果揭示了云贵高原碳储量与生境质量演变规律及分布格局,可为该区生态环境建设提供科学依据.
Abstract
The karst geological conditions of the Yunnan-Guizhou Plateau have led to serious rocky desertification and fragile ecological environment.Evaluating the ecosystem service function of the region can help to improve ecological environment problems.Based on the InVEST model and PLUS model,the carbon stock and habitat quality of the Yunnan-Guizhou Plateau from 2000 to 2030 are quantitatively evaluated.Combined with natural resource zoning,the temporal and spatial variation characteristics and driving factors of carbon stock and habitat quality in the region from 2000 to 2030 are analyzed.The results show that from 2000 to 2030,the average carbon stock of the Yunnan-Guizhou Plateau is 7.323×109 t,showing a downward trend over the years,with a total reduction of 0.471×109 t.Spatially,it was characterized by high in the west and low in the east.The highest fourth-level zoning was the subdivision of the northern part of Chuxiong in the eastern part of Lijiang City.The land type with the highest contribution to carbon stock was the forest land(>60%),followed by cultivated land(>28%).The factor with the strongest explanatory power for the spatial differentiation of carbon stocks was elevation,and the factor with the strongest interaction was land use and slope direction.From 2000 to 2030,the average habitat quality of the Yunnan-Guizhou Plateau is 0.755,showing a downward trend over the years,with a total reduction of 0.016.Spatially,it was characterized by high in the west and low in the middle and east.The highest fourth-level zoning was the subdivision in the west of Lijiang City and the southeast of Nujiang Lisu Autonomous Prefecture.The habitat quality of forest land is the highest,with an index of 0.83.The research results reveal the evolution law and distribution pattern of carbon stock and habitat quality on the Yunnan-Guizhou Plateau,which can provide a scientific basis for the ecological environment construction of the region.
