环境资产是指自然环境或人类活动形成的，具有经济价值的自然资源、生态系统和环境服务。这些环境资产不仅对人类的生产和生活具有重要意义，也是环境可持续发展的基础。

环境资产包括可更新资源和不可更新资源。可更新资源是指能够在一定时间内自然恢复或人工再生的资源，如水资源、森林资源、草地资源等；不可更新资源则是指经过长时间地质作用形成的资源，如矿产资源、油气资源等。这些环境资产在人类的生产生活中扮演着重要的角色，例如水资源是农业灌溉和工业生产的基础，森林资源是重要的生态系统和木材来源，油气资源则是重要的能源来源。

环境资产的经济价值主要体现在以下几个方面：一是直接使用价值，即利用这些资源直接进行生产和生活所产生的经济效益；二是间接使用价值，即这些资源对环境和生态系统的作用所产生的生态效益；三是选择价值，即未来世代对这些资源的继承和利用所产生的潜在经济效益。

保护和管理好环境资产对于实现可持续发展至关重要。通过对环境资产的科学管理和合理利用，可以最大程度地发挥其使用价值，避免过度开采和环境破坏，保障经济社会的可持续发展。

英文：

Environmental assets refer to natural resources, ecosystems, and environmental services formed by the natural environment or human activities that have economic value. These environmental assets are not only of great significance to human production and life but also the basis for sustainable environmental development.

Environmental assets include renewable resources and non-renewable resources. Renewable resources refer to resources that can naturally recover or be regenerated artificially within a certain period of time, such as water resources, forest resources, grassland resources, etc.; non-renewable resources refer to resources formed through long-term geological processes, such as mineral resources, oil and gas resources, etc. These environmental assets play an important role in human production and life, for example, water resources are the basis of agricultural irrigation and industrial production, forest resources are important ecosystems and sources of timber, and oil and gas resources are important energy sources.

The economic value of environmental assets is mainly reflected in the following aspects: first, the direct use value, which is the economic benefits generated by directly using these resources for production and life; second, the indirect use value, which is the ecological benefits generated by the role of these resources in the environment and ecosystem; third, the option value, which is the potential economic benefits generated by future generations inheriting and utilizing these resources.

Protecting and managing environmental assets is crucial for achieving sustainable development. Through scientific management and rational utilization of environmental assets, their use value can be maximized, excessive exploitation and environmental damage can be avoided, and sustainable economic and social development can be guaranteed.
