An Individual Rural Geography

To date, only limited research has focused on the individual in rural geography compared to the importance given to the rural community. With the sociocultural turn and moral positions in rural geography, however, the individual is acquiring more relevance but encapsulated in analytical traditions of locality community and of marginal situations and people. This article synthesizes the most significant works about the individual, especially within rural geography, and its key dimensions are identified: citizenship (political and normative dimension), emotional aspects (the extraordinary moments in peoples' lives), everyday life (the relationship between the individual and the rural place), and difference and otherness (between and within others). To develop an individual rural geography, these four dimensions, which reflect different aspects of the rural individual, must be used in a complementary manner. The relevance of each dimension suggests different types of individualities in rural areas. Ultimately, this article proposes a “new humanism” in contrast with antihumanistic poststructural approaches.     

Spatiotemporal change patterns of urban lakes in China’s major cities between 1990 and 2015

China has experienced unprecedented urbanization in the past decades, resulting in dramatic changes in the physical, limnological, and hydrological characteristics of lakes in urban landscapes. However, the spatiotemporal dynamics in distribution and abundance of urban lakes in China remain poorly understood. Here, we characterized the spatiotemporal change patterns of urban lakes in China’s major cities between 1990 and 2015 using remote-sensing data and landscape metrics. The results showed that the urban lake landscape patterns have experienced drastic changes over the past 25 years. The total surface area of the urban lakes has decreased by 17,620.02?ha, a decrease of 24.22%, with a significant increase in the landscape fragmentation and a reduction in shape complexity. We defined three lake-shrinkage types and found that vanishment was the most common lake-shrinkage pattern, followed by edge-shrinkage and tunneling in terms of lake area. Moreover, we also found that urban sprawl was the dominant driver of the lake shrinkage, accounting for 67.89% of the total area loss, and the transition from lakes to cropland was also an important factor (19.86%). This study has potential for providing critical baseline information for government decision-making in lake resources management and urban landscape design.     

Modelling coastal land use change by incorporating spatial autocorrelation into cellular automata models

This paper presents a spatial autoregressive (SAR) method-based cellular automata (termed SAR-CA) model to simulate coastal land use change, by incorporating spatial autocorrelation into transition rules. The model captures the spatial relationships between explained and explanatory variables and then integrates them into CA transition rules. A conventional CA model (LogCA) based on logistic regression (LR) was studied as a comparison. These two CA models were applied to simulate urban land use change of coastal regions in Ningbo of China from 2000 to 2015. Compared to the LR method, the SAR model yielded smaller accumulated residuals that showed a random distribution in fitting the CA transition rules. The better-fitting SAR model performed well in simulating urban land use change and scored an overall accuracy of 85.3%, improving on the LogCA model by 3.6%. Landscape metrics showed that the pattern generated by the SAR-CA model has less difference with the observed pattern.

城市居民对乡村旅游影响的感知研究——以上海、南京为例

乡村旅游的发展必然会对乡村经济、社会文化和环境产生影响.以2006年9-11月在上海、南京两城市所作的700份问卷调查资料为基础,利用SPSS和Excel软件,定量分析了城市居民对乡村旅游影响的感知.结果表明:城市居民对乡村旅游影响正面感知强于负面感知;可分为中立者(37.3%)、理性支持者(37.8%)和矛盾支持者(24.9%)3类,支持者多于中立者;人口学特征不同,其感知存在一定差异.     

3S技术在神农架滑雪场生态环境影响评价中的应用

神农架滑雪场位于国家级自然保护区的边缘地带。运用景观生态学原理和方法,采用3S技术,对滑雪场景观生态体系的结构和功能状况进行评价,通过景观多样性指数、景观聚集度指数等指标量化计算及比较分析,预测了项目建成后对所在区域生态完整性的影响程度及将造成的敏感生态问题。结果表明,评价区自然系统的生物量将减少430.26 t,平均净生产力降低为881.55 g/m2.a,项目建设不会改变林地的模地地位,其对生态环境质量仍有较强的调控能力。3S技术结合景观生态学方法将生态环境影响评价由定性评价转向定量预测,为建设项目生态影响评价研究作了有益的探索。
