生态治理技术适宜性评价影响因素及概念模型——以沙漠化治理技术为例 [PDF]
, 2020 生态系统退化已是全球的主要环境问题,旨在恢复和重建生态系统的生态治理技术受到重视。在众多直接、间接的技术中,如何遴选最适宜的技术,目前仍缺乏系统、科学、完善的评价方法。根据对其他领域中有关技术评价理论、方法、要素等的梳理,以沙漠化治理技术涉及的多个影响因素为例,首次提出一般性生态治理技术适宜性评价概念模型——"双圈十二维"模型,包括两类十二个维度:(1)内生因素(内圈):限制性、独立性、经济性、可操作性;(2)外部因素(外圈):目标、地域、时效、政治政策制度 ...

人工藻结皮形成过程中表土非降雨型水分吸收的变化情况 [PDF]
, 2010 在干旱、半干旱地区,表土非降雨型水分吸收对于植物、生物结皮以及一些小型动物都起着非常重要的作用.本研究对库布齐沙漠中各种水分吸收类型进行了调查,并对人工结皮形成过程中水分吸收的变化进行了跟踪监测.结果发现,在实验区,从空气中吸收的水分占表土水分吸收量的25.07%~39.83%,其主要是通过水汽吸附机制进行.相比之下,表土从深层土壤吸收的水分更多,大约占到水分吸收量的60.17%~74.93%.人工结皮的形成促进了表土水分的吸收,但吸收水分的增加并非在接种后或结皮形成后立即表现出来,而是在结皮形成后 ...
