1国家公园原住居民的生态阈值及其守护作用——自然-文化双资源视域显示文摘国家公园的原住居民是自然和文化资源的双重守护者,但同时也会对自然生态造成一定的负面影响,留下守护者的生态足迹,因此需要确定国家公园生态承载力约束下的原住居民的生态阈值。首先,从自然和文化双重守护的视域研究国家公园容纳原住居民的现状与机理,以及由此引发的实际问题和科学问题。其次,根据生态足迹理论,分别建立国家公园生态承载力、原住居民生态足迹和生态阈值的分析框架与测算模型。再次,以武夷山国家公园为例进行实证研究,表明上述测算方法具有良好的可行性和有效性。最后,根据超循环经济理论,构建国家公园自然与文化双重保护的超循环模型,揭示对原住居民进行科学管理的基本原理。张智光 张俞 2022东南大学学报(哲学社会科学版)2022,24,5:2
2Evolution of Neolithic site distribution(9.0–4.0 ka BP) in Anhui,East China显示文摘Based on archaeological surveys of Neolithic cultural development and GIS spatial analysis,this study reproduced the main characteristics of temporal distribution and settlement selection of the sites from the Neolithic Age in Anhui and identified a relationship between environmental evolution and human activity.The results show that altitude,slope direction,and slope gradient were consistent among the settlements at different stages of the Neolithic Age in Anhui,and the sites were mostly distributed in hilly and plain areas on southeast-or south-facing slopes of low gradients close to rivers.We determined that early Neolithic Age(9.0–7.0 ka BP) sites were scattered in small numbers and likely had little cultural exchange with communities of other provinces.The environmental characteristics of various regions in Anhui indicated that the climate was warm and humid with extensive water distribution.The sites of the mid Neolithic Age(7.0–5.0 ka BP) increased rapidly with wide distribution.They were mainly distributed in the plain area north of the Huaihe River and the southwestern areas of Anhui.In the mid Neolithic Age,the warm and humid climate gradually dried,and our ancestors slowly developed cultural exchanges.The largest number of sites existed during the late Neolithic Age(5.0–4.0 ka BP),and were distributed throughout the province.During this period,the overall climate was relatively dry,but humans could still obtain water and other resources through migration.The relatively benign climate facilitated cultural interaction and exchange,which increased during this time,and the Wanjiang culture matured.We also determined that as early civilization evolved,cultures in different regions responded differently to environmental changes.In humid subtropical regions,especially in low-lying plains and areas beside lakes,rivers,and coastal areas,the relatively dry climate in the late period of the middle Holocene,prefaced by a period of high humidity,was conducive to the development of human culture.The evidence from the Neolithic settlements in Anhui therefore reflects this subtropical man-land relationship between cultural development and environmental conditions.WU Li SUN Xiaoling SUN Wei ZHU Cheng ZHU Tongxin LU Shuguang ZHOU Hui GUO Qingchun GUAN Houchun XIE Wei KE Rui LIN Guiping 2020Journal of Geographical Sciences2020,30,9:2
