| 1 | Vulnerability and Sustainable Development Mode of Coal Cities in Northeast China显示文摘In this study, by carrying on the spot investigation to the seven coal cities in Northeast China and interview-ing with the local authority and the residents, the authors definite the vulnerability that is closed to exposure, sensitiv-ity and resilience, and set up vulnerability model of coal cities in Northeast China. At the same time, the authors broadly illustrate how the components of natural-social-economic system act in the coal area, so as to probe the ways to reduce vulnerability more effectively, such as preferential national policy and so on. Furthermore, the article studies the relationship between vulnerability and sustainable development. Vulnerability is a spatio-temporal function of sus-tainable development. The regional sustainable development refrains the spiral ascending of vulnerability. And the re-gional vulnerability and sustainable development appear in turn. Then the article analyzes the natural vulnerability, so-cial vulnerability and economic vulnerability of coal cities in Northeast China. At last, combing vulnerability model and situation of coal cities in Northeast China, the authors put forward regional technology innovation mode, multi-dimension structure transformation mode, attracting investment mode and recycling economy mode to reduce vulnerability. | LI Bo TONG Lianjun | 2008 | Chinese Geographical Science2008，18，2： | 9 |
| 2 | High-quality de novo assembly of the Eucommia ulmoides haploid genome provides new insights into evolution and rubber biosynthesis显示文摘We report the acquisition of a high-quality haploid chromosome-scale genome assembly for the first time in a tree species,Eucommia ulmoides,which is known for its rubber biosynthesis and medicinal applications.The assembly was obtained by applying PacBio and Hi–C technologies to a haploid that we specifically generated.Compared to the initial genome release,this one has significantly improved assembly quality.The scaffold N50(53.15 MB)increased 28-fold,and the repetitive sequence content(520 Mb)increased by 158.24 Mb,whereas the number of gaps decreased from 104,772 to 128.A total of 92.87%of the 26,001 predicted protein-coding genes identified with multiple strategies were anchored to the 17 chromosomes.A new whole-genome duplication event was superimposed on the earlierγpaleohexaploidization event,and the expansion of long terminal repeats contributed greatly to the evolution of the genome.The more primitive rubber biosynthesis of this species,as opposed to that in Hevea brasiliensis,relies on the methylerythritol-phosphate pathway rather than the mevalonate pathway to synthesize isoprenyl diphosphate,as the MEP pathway operates predominantly in trans-polyisoprene-containing leaves and central peels.Chlorogenic acid biosynthesis pathway enzymes were preferentially expressed in leaves rather than in bark.This assembly with higher sequence contiguity can foster not only studies on genome structure and evolution,gene mapping,epigenetic analysis and functional genomics but also efforts to improve E.ulmoides for industrial and medical uses through genetic engineering. | Yun Li Hairong Wei Jun Yang Kang Du Jiang Li Ying Zhang Tong Qiu Zhao Liu Yongyu Ren Lianjun Song Xiangyang Kang | 2020 | Horticulture Research2020，7，1： | 7 |
| 3 | Decomposition Analysis on Direct Material Input and Dematerialization of Mining Cities in Northeast China显示文摘Material dematerialization is a basic approach to reduce the pressure on the resources and environment and to realize the sustainable development. The material flow analysis and decomposition method are used to calculate the direct material input (DMI) of 14 typical mining cities in Northeast China in 1995–2004 and to analyze the demateri- alization and its driving factors in the different types of mining cities oriented by coal, petroleum, metallurgy and multi-resources. The results are as follows: 1) from 1995 to 2006, the increase rates of the DMI and the material input intensity of mining cities declined following the order of multi-resources, metallurgy, coal, and petroleum cities, and the material utilizing efficiency did following the order of petroleum, coal, metallurgy, and multi-resources cities; 2) during the research period, all the kinds of mining cities were in the situation of weak sustainable development in most years; 3) the pressure on resources and environment in the multi-resources cities was the most serious; 4) the petro- leum cities showed the strong trend of sustainable development; and 5) in recent years, the driving function of eco- nomic development for material consuming has continuously strengthened and the controlling function of material utilizing efficiency for it has weakened. The key approaches to promote the development of circular economy of min- ing cities in Northeast China are put forward in the following aspects: 1) to strengthen the research and development of the technique of resources’ cycling utilization, 2) to improve the utilizing efficiency of resources, and 3) to carry out the auditing system of resources utilization. | QIU Fangdao TONG Lianjun ZHANG Huimin ZHANG Na | 2009 | Chinese Geographical Science2009，19，2： | 4 |

| 5 | Spatial-temporal Characteristics of Green Development Efficiency and Influencing Factors in Restricted Development Zones:A Case Study of Jilin Province,China显示文摘Green development is an important issue of sustainable development in China.Due to the relatively backward economy and the fragile ecological environment,restricted development zones need to embrace green development.Taking 38 counties in Jilin Province as the empirical research objects,and based on cross-sectional data for each county in 2005,2010,and 2015,we accurately depicted the spatiotemporal evolutionary characteristics of green development efficiency(GDE)in restricted development zones of Jilin Province using the slacks-based measure-data envelope analysis(SBM-DEA)model.Moreover,the factors that influence GDE were further analyzed using the Tobit model.We found that:first,GDE showed a V-shaped trend in restricted development zones of Jilin Province.The differences in GDE in the eastern,central,and western Jilin Province increased gradually.Second,76%of counties in the restricted development zones had high or higher efficiencies.The resource-based cities were the main areas with low or lower GDE.Third,the economic development level was the core factor affecting GDE.Urbanization level had a significant negative effect on GDE in the restricted development zones.The effect of technological innovation level on GDE fluctuated,and we found that a‘backward mechanism’of technological innovation was beginning to form.Industrial structure and environmental governance had no significant effects on GDE. | LI Ping TONG Lianjun GUO Yanhua GUO Fuyou | 2020 | Chinese Geographical Science2020，30，4： | 0 |
| 6 | Green Development for Supporting Sustainability of Northeast China:Performance Quantification,Spatio-temporal Dynamics and Implications显示文摘Green development is the cognition of geography to human-nature nexus under the background of the new era.As China is facing various eco-environment problems,green development has become a key approach towards ecological progress,and it is ultimately an explicit means to respond to support sustainable development in China.Quantifying green development performance is essential to track efforts towards sustainability and guide policymakers.However,applying the balanced property of’Economy-Ecology-Society’of green development to its performance assessment is rarely discussed.Here we elaborated the connotation of green development and developed a quantification model with coupling coordination degree to assess green development performance of the largest old industrial base of China,Northeast China.We found that the green development performance has been improved from a score of 0.443 in 2003 to 0.530 in 2019 but the disparities of green development performance were enlarging over time,especially for the cities in Heilongjiang.A positive spatial autocorrelation phenomenon of green development performance was confirmed,and Low-Low clusters in the northeastern Heilongjiang and High-High clusters in the central-eastern Liaoning were discovered.This study suggests the need to track the spatio-temporal dynamics of green development performance to provide references for achieving sustainable development goals in northeast China and other regions. | FAN Weiguang ZHANG Pingyu TONG Lianjun LI Chenggu LI Xin LI Jing MA Zuopeng | 2022 | Chinese Geographical Science2022，32，3： | 0 |
