概括
保护规划面临着保护生物多样性的挑战. 虽然17%的土地可以保护67%的植物物种和许多脊椎动物,但实现"生物多样性公约" (CBD) 区域和物种保护目标仍然是复杂的.
科学领域:
- 保护生物学 保护生物学
- 生物多样性保护 生物多样性保护
- 保护区是保护区.
背景情况:
- 有效的保护规划需要确定物种保护的关键区域.
- 生物多样性公约 (CBD) 的目标是17%的陆地保护和60%的植物物种覆盖.
- 评估这些区域和物种保护目标的兼容性至关重要.
研究的目的:
- 评估"生物多样性公约" (CBD) 保护区规模和物种覆盖面的目标的兼容性.
- 确定当前的土地保护水平是否与保护植物和脊椎动物多样性的目标保持一致.
主要方法:
- 对拟议保护区的物种分布数据进行空间分析.
- 评估高生物多样性地区与现有/拟议保护区之间的重叠情况.
主要成果:
- 百分之六十七的植物物种在仅占陆地表面17%的区域内发现.
- 这些关键地区还包括大多数具有有限地理范围的陆地脊椎动物.

What is Conservation Biology?
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.
Biodiversity and Human Values
Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.
Plant Breeding and Biotechnology
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
Conservation of Declining Populations
Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.
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.
