辽宁本溪国家地质公园旅游环境容量计算

地质公园的规划必须预测游客规模和环境容量,遵循“在保护中开发,在开发中保护”的原则,使地质公园的旅游资源得到可持续发展;总结国内外对于环境容量的概念理论和计算方法,指出原始公式的缺陷,采用整个景区的平均游览时间为计算指标的修订公式,对于不同景区分别使用面积或线路容量计算方法,计算出本溪国家地质公园环境日容量和年容量分别为10 593人和2 587 870人。     

珠江三角洲地区土地资源承载力研究

从珠江三角洲的主要特点，提出土地承载力的新定义和珠江三角洲地区土地资源承载力计算的新思路。并据新近资料，对珠江三角洲9市进行计算评价，结果表明：各市土地资源承载力高低不同，深圳人口超载，东莞、广州处在临界边缘，其他区域还有不同程度的剩余。

基于“双评价”的永久基本农田划定研究 ——以黄石市为例

研究目的：探索基于“资源环境承载力和国土空间开发适宜性评价”下的永久基本农田划定方法,为区域国土空间用途管制和永久基本农田划定提供参考。研究方法：在“双评价”的基础上,构建“承载力—适宜性—质量”三位一体的永久基本农田划定技术模型,并以黄石市为例开展永久基本农田划定实证研究。研究结果：（1）基于“短板理论”,考虑限制性因素和驱动性因素,建立耕地资源承载力评价指标体系,并在承载力基础上完成农业生产适宜性评价,从生态保护功能角度开展生态保护适宜性评价;（2）永久基本农田划定方法充分考虑了资源环境对耕地生产稳定性的约束作用,确保了耕地生产功能稳定发挥,同时统筹兼顾了生态保护与基本农田保护的需求,优化了国土空间格局;（3）结合耕地质量对黄石市耕地进行分区,划分为优先保护区、适宜保护区、后备调控区、生态退耕区4类,在耕地分区基础上综合划定永久基本农田。研究结论:该方法能够统筹区域生态保护与耕地保护双重目标,为优化国土空间开发保护格局提供了新思路。     

汽车装配物流输送机系统结构的优化设计与应用

通过对输送机承载小车轴承提前失效现象的理论分析,得出其主要失效原因是轴承自身强度不足及润滑不良。由此症结寻求对策：设计非标整体轴承滚轮,辅以油嘴油槽加注油脂以改善轴承润滑,从而达到延长轴承使用寿命的目的。     

析生态城市水休闲旅游环境承载力评价——以扬州古运河风景区为例

水休闲旅游是城市规划中的新兴主题,而水休闲旅游本身的规划模式和经营水平直接影响城市发展的生态循环程度。旅游活动的发展势必造成对城市水域空间环境质量的影响,空间旅游环境的承载力研究也成为旅游规划的重要前提。本文以扬州古运河风景区为例,在分析景区地理资源和旅游经济条件的基础上构建水休闲旅游环境承载力测算指标,并利用木桶综合推测法计算出风景区水休闲旅游环境综合承载力,为生态循环型城市水休闲旅游规划步骤中的开发条件评价提供合理依据。     

退耕还林对农户生态承载力影响分析——以陕西吴起县为例

运用生态足迹的方法从供给的角度测算了退耕还林还草工程对陕西吴起县农户户均生态承载力的影响,测算结果表明:退耕还林之前吴起县户均生态承载力为2.57 hm2,退耕之后户均生态承载力为3.62 hm2,上升了1.05 hm2;由耕地、林地、草地组成的户均生态承载力供给结构发生了变化,由退耕还林前的27.01∶1.01∶1变为退耕还林后的4.82∶13.93∶1,说明退耕还林工程对吴起生态经济的容纳能力有所增加,生态供给结构趋于优化。对耕地、林地、草地因子进行生态承载力敏感性分析结果表明:林地因子是影响退耕还林之后户均生态承载力的主要因子。最后,对进一步提升吴起县户均生态承载力的方法进行了探索。

A “load-carrier” perspective approach for assessing tourism resource carrying capacity

To address the challenge of global tourism resources being overloaded or underutilization, there requires an adequate method for assessing the tourism resource carrying capacity (TRCC). However, the majority of previous evaluation perspectives on TRCC are limited by thresholds. This paper develops an innovative approach for assessing TRCC from the “load-carrier” perspective. TRCC is assessed by exploring the interaction between the carriers and loads of tourism resources. Chongqing city in China is employed as the case city to demonstrate the application of the established TRCC method. The conclusions are as follows: 1) This study elaborates the new connotation of TRCC from the perspective of “load-carrier”, and establishes the TRCC evaluation system based on the dynamic relationship between the carrier and load of tourism resources. 2) The proposed TRCC evaluation method is proved effective through an empirical study of Chongqing. 3) Chongqing's case unveils that the overload performance of TRCC can be dynamically monitored and predicted. By applying the TRCC evaluation methodology developed in this study, tourism managers and policymakers can identify whether it is the load or the carrier of tourism resources that affect the performance of TRCC, thereby taking targeted policy measures to eliminate potential risks of overload or underutilization.     

Impact of walking speed on tourist carrying capacity: The case of Maiji Mountain Grottoes,China

This paper analyzes the impact of walking speed on tourist carrying capacity. To do so, a combination of simulation experimentation and on-the-ground experiment is suggested to work in a study case, Maiji Mountain Grottoes, China. The simulation findings indicate that walking speed has a negative impact on tourist carrying capacity and the correlation coefficient is 0.64, for the reason that walking takes up more space. The on-the-ground experiment shows that carrying capacity is not a unified limit all over a destination, but changeable temporally and spatially, and its estimation needs to be adjusted according to the minimum area required per tourist and tourist activity. The method applied in this paper and the simulation findings can serve as a methodological tool for further research about tourist carrying capacity where the main activity of tourists is walking while watching.
