【良好农业规范对土壤生物多样性的贡献】良好的农业做法通过其对土壤性质、制度和生物多样性的直接影响而具有高度重要性。本研究评估了不同土壤耕作类型的良好农业措施——常规、最少耕作、覆盖、免耕和有机耕作对土壤环境的影响。研究表明，这些措施对土壤含水量、生物多样性和土壤结构稳定性具有积极的影响。研究人员表示其研究结果可为进一步确定土壤与自然和谐、可持续的耕作方式提供参考。相关研究论文已发表在《Open Journal of Ecology》上。DOI: 10.4236/oje.2021.111007 https://t.cn/A65Loph9

【Necessary Conditions and Situational Variables of Payments for Ecosystem Services】

Ecosystem services (ES) are the fund-service resources that human beings acquire from the ecosystem. Changes in ES have serious impacts on human well-being. Payment for ecosystem services (PES) is an institutional arrangement that provides ES suppliers with positive financial incentives. PES schemes are attracting more and more attention from scholars and conservationists. This article proposes an analytical framework for the emergence of PES and argues that the key to determining whether PES can occur and whether a selected PES program is appropriate is to evaluate the net gain. And the cost and income composition of different types of PES are analyzed, and an investment model is used to describe them.
