概括

本研究引入了综合生态系统服务指数 (IESI),以量化区域生态系统服务,发现水产,息地质量和土壤保护增加,而云南省中部的碳储存减少.

科学领域:

环境科学环境科学
生态生态学生态生态学
地理空间分析的研究.

背景情况:

区域生态系统服务 (ES) 管理需要理解ES的动态特征,并整合多样化的评估结果.
目前用于整合和客观评估多个ES的方法有限.

研究的目的:

评估从2000年到2020年在中云南省 (CYP) 的四个关键ES (水产,碳储存,息地质量,土壤保护).
构建一个综合生态系统服务指数 (IESI) 进行全面的ES评估.
使用基于最佳参数的地理探测器模型 (OPGD) 识别ES空间分歧的驱动因素.

主要方法:

用于ES评估的InVEST和RUSLE模型.
对于IESI建设的主要组件分析 (PCA).
在最佳空间尺度 (4500m x 4500m网格) 的OPGD识别驱动因素.

主要成果:

该IESI有效地将四个关键ES集成到CYP中.
水产,息地质量和土壤保护呈现上升趋势;碳储存减少.
IESI最初下降,然后增加,平均值从0.6650到0.7338.8不等.
陆地表面的浮标度,斜率和NDVI是综合生态系统服务 (CES) 空间分歧的主要驱动因素.

结论:

IESI提供了一种科学和有效的方法来评估区域CES.
这种方法为平衡土地使用竞争和评估政策有效性提供了一个全面的工具.

关键词:

在InVEST模型中,综合生态系统服务指数 (IESI)驱动力分析驱动力分析规模效应是一个规模效应.中央云南省 (CYP) 是一个省.

Ecological Niches

Ecological Niches

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

The Soil Ecosystem

The Soil Ecosystem

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

What is Biodiversity?

What is Biodiversity?

Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.
