Understanding the spatial variation,temporal changes,and their underlying driving forces of carbon sequestration in various forests is of great importance for understanding the carbon cycle and carbon management options.How carbon density and sequestration in various Cunninghamia lanceolata forests,extensively cultivated for timber production in subtropical China,vary with biodiversity,forest structure,environment,and cultural factors remain poorly explored,presenting a critical knowledge gap for realizing carbon sequestration supply potential through management.Based on a large-scale database of 449 permanent forest inventory plots,we quantified the spatial-temporal heterogeneity of aboveground carbon densities and carbon accumulation rates in Cunninghamia lanceolate forests in Hunan Province,China,and attributed the contributions of stand structure,environmental,and management factors to the heterogeneity using quantile age-sequence analysis,partial least squares path modeling(PLS-PM),and hot-spot analysis.The results showed lower values of carbon density and sequestration on average,in comparison with other forests in the same climate zone(i.e.,subtropics),with pronounced spatial and temporal variability.Specifically,quantile regression analysis using carbon accumulation rates along an age sequence showed large differences in carbon sequestration rates among underperformed and outperformed forests(0.50 and 1.80 Mg·ha^(-1)·yr^(-1)).PLS-PM demonstrated that maximum DBH and stand density were the main crucial drivers of aboveground carbon density from young to mature forests.Furthermore,species diversity and geotopographic factors were the significant factors causing the large discrepancy in aboveground carbon density change between low-and high-carbon-bearing forests.Hotspot analysis revealed the importance of culture attributes in shaping the geospatial patterns of carbon sequestration.Our work highlighted that retaining largesized DBH trees and increasing shade-tolerant tree species were important to enhance c

Science China Earth Sciences 2021年第2期64卷 307-317页

As the most fundamental economic sector of human societies,farming has played a significant role in interactions between humans and the environment.The study of crop patterns in various regions could not only clarify the economic foundations of early societies,but also greatly improve our understanding of interactions among human beings,the environment,and other creatures.In this regard,this study focuses on early agriculture practices at the Haojiatai site,situated in the cultural and natural transitional region between North and South China.Macro plant remains from this site reveal that foxtail millet was the most important staple crop here during the Longshan and Xinzhai periods(4300–3800 cal.yr BP),along with common millet and a small amount of rice and soybean.This crop pattern is in contrast to the ancient environmental conditions of this region,and cultural factors such as agriculture traditions and food preferences may have been more important in the formation process of this crop pattern.

A Study of Sanxingdui Museum’s Building of International Communication Capacity

引用

Contemporary Social Sciences 2022年第5期7卷 104-117页

作者： Zhou Lijuan Sichuan Museum ChengduSichuan610072China

Museums’building of international communication capacity has become a hot topic in museology.Featuring unique resources of ancient Shu culture,Sanxingdui Museum is of great value in international communication.This paper first reviews previous studies in this area,then analyzes the efforts made by present-day museums in China and abroad to raise their international profile,and later probes into the current status of Sanxingdui Museum’s building of international communication capacity.On this basis,this paper summarizes the countermeasures Sanxingdui Museum took and proposes suggestions regarding the building of its international communication capacity.Sanxingdui Museum should work harder to improve its overseas exhibitions,protect and study its cultural relics,advance the application for World Heritage status,and promote the Sanxingdui brand via multimedia.

关键词： Sanxingdui Museum international communication cultural influence exchanges and mutual learning

文化软实力在当今国际竞争中起到越来越重要的作用，但相比较于经济影响力，我国的文化影响力还有待提升；错综复杂的国际国内背景对我国现阶段提升国家凝聚力，提升国民的文化认同和文化自信，强化民族身份以及构建文化价值提出了更高的要求。基于这样的认识，以“国家纪念地”的概念为关注点，审视国际发达国家在国家纪念地等方面的实践，希望为中国及首都地区的建设提供新的思路和发展路径。比较研究的对象主要包括：美国、法国和英国等。

关键词：国家纪念地文化影响力首都地区　　National Memorial Sites cultural influence Capital Region
