红色旅游发展效率评价及影响因素研究——以黔北黔西红色旅游区为例

红色旅游发展效率表征旅游区红色旅游高质量发展水平。以黔北黔西红色旅游区为研究对象,借助DEA模型及Malmquist指数对2014—2019年该区域17个县（市、区）的红色旅游发展效率进行测度,同时利用核密度函数和多元线性回归模型分别剖析了其空间演化特征与关键影响因素。研究发现：（1）研究区域内红色旅游发展效率整体偏低,受技术进步的积极影响,多数县（市、区）红色旅游发展效率呈稳步提升状态;（2）红色旅游发展效率具备空间集聚性和异质性的特征,整体呈现“M”型双峰分布,区域分布差异较大;（3）技术创新、红色旅游资源优势度、交通便利性是影响该区域红色旅游发展效率的主要因素,政府对旅游经济干预程度、经济发展水平和人才规模对该区域红色旅游发展效率的影响较小,产业结构对改善该区域红色旅游发展效率的积极影响尚未凸显。     

The Chinese western development initiative: new opportunities for mineral investment

The Western Development Initiative (WDI), launched in 2000 by the Chinese Government, will greatly change the modes and improve the quality of life of the 355 million people living in the western region of China. This paper presents a panoramic picture of the mineral industries under the framework of the WDI. First, it gives an overview of the WDI, including a summary of the favorable and unfavorable conditions for the WDI, the objectives, priorities and key geographical areas for the WDI and the national policies and measures for implementing the WDI. Second, it describes the roles of the mineral industries in the WDI. Finally, it details the policies and actions of the Chinese Government on the exploration and development of mineral resources in the western region in support of the WDI.     

火山灰下的记忆──辽西中生代热河化石库的组成和形成

燕山期环太平洋构造活动导致辽西频繁地火山喷发。巨星火山灰一次次覆盖火山周围丛林和湖沼．掩埋了各种生物，形成学术价值极高的化石库（fossillagerstatte），尤其是鸟类和昆虫化石及动物的毛发、羽毛、膜翅及内脏等软组织结构，都或多或少地以精细的碳化膜或印痕保存。特别是近年一系列新发现，如孔子鸟（Confucinsornis）和带毛的秀颌龙（Compsognathus）／中华龙鸟（Sinosauroteryx）等，引起国内外学术界的轰动。笔者研究了其中一批化石，从古生态和埋藏事件进行探讨认为：（1）该生物群代表分子中鹦鹉嘴龙（Psittacosaurus）、带毛秀颌龙／中华龙鸟及孔子鸟等，很可能是温血动物。（2）频繁的火山喷发不但将巨量的火山灰沉积在广大的湖泊丛林区，加快了其沼泽化的进程，对煤层及油页岩层的形成起了催化作用。     

西太湖区域水环境容量分配及水质可控目标研究

西太湖流域产业、人口集聚,水环境污染一直以来是该区域经济可持续发展的制约因素之一,利用2010年的监测数据对西太湖主要入湖河流及湖体的水环境状况进行了分析,通过对研究区域工业点源、城镇和农村生活源、农田面源和畜禽水产污染源排污的分布情况调查,并计算了入河污染物量;利用构建的西太湖区域水量水质数学模型,估算了区域水环境容量,依据水环境功能区的水质目标与水域面积分配到了各市/区,在充分调查现有与规划的各类型污染源总量控制工程措施的基础上,量化出具有空间分布的流域污染削减率,并提出水质可控目标。结果表明:太湖湖体受总氮污染影响总体水质劣于Ⅴ类,研究区域主要入湖河流基本处于Ⅳ类,氨氮超标最严重;进入水体的COD为25 410.2 t/a,氨氮2 795.4 t/a,总氮4 646.4 t/a,总磷313.8 t/a,其中城镇生活源污染物入河量所占的比例最大,各类污染物均在35%~50%,尤以宜兴市和常州武进区负荷较大;各控制单元进入水体的污染物量基本都超过了水环境容量,近期各市/区COD、氨氮、总氮和总磷的削减率分别为8.0%~56.0%,8.0%~62.1%,6.0%~41.8%,8.0%~59.9%,远期污染物削减率更高;最终通过模型推算,定出西太湖湖体各污染因子的可控目标,2015年,COD、氨氮、总氮和总磷分别为4.50、0.80、3.50和0.08 mg/L,2020年进一步达到4.50、0.60、3.00和0.07 mg/L,为西太湖总量控制提供科学依据。

Accounting for Complementarity to Maximize Monitoring Power for Species Management

To choose among conservation actions that may benefit many species, managers need to monitor the consequences of those actions. Decisions about which species to monitor from a suite of different species being managed are hindered by natural variability in populations and uncertainty in several factors: the ability of the monitoring to detect a change, the likelihood of the management action being successful for a species, and how representative species are of one another. However, the literature provides little guidance about how to account for these uncertainties when deciding which species to monitor to determine whether the management actions are delivering outcomes. We devised an approach that applies decision science and selects the best complementary suite of species to monitor to meet specific conservation objectives. We created an index for indicator selection that accounts for the likelihood of successfully detecting a real trend due to a management action and whether that signal provides information about other species. We illustrated the benefit of our approach by analyzing a monitoring program for invasive predator management aimed at recovering 14 native Australian mammals of conservation concern. Our method selected the species that provided more monitoring power at lower cost relative to the current strategy and traditional approaches that consider only a subset of the important considerations. Our benefit function accounted for natural variability in species growth rates, uncertainty in the responses of species to the prescribed action, and how well species represent others. Monitoring programs that ignore uncertainty, likelihood of detecting change, and complementarity between species will be more costly and less efficient and may waste funding that could otherwise be used for management.

Coordinated management of energy and mineral resources development and control of pollution in Western China

Natural environment is fragile and harsh in Western China where rich energy and mineral resources are endowed,enabling energy and mining development to become a pillar industry of the regions socioeconomic development This paper identified the key issues and challenges faced by eco-environment as a result of energy and mining development in Western China.We argued mat mining and energy development have caused various environmental problems,and that environmental degradation is increasingly prominent in Western China,hence,we request coordinated resource development and environmental protection for sustainable development in this region.Based on the above recognitions,this paper put forward relevant policy recommendations:promoting green development vigorously and developing new green energy;formulating and enforcing environmental protection laws and regulations,improving ecological compensation mechanism;establishing green threshold;strengthening integration between western resource-based cities and coastal region to get rid of the"resource curse";improving energy and mineral resources development stakeholders’involvement;coordinating resource taxes and local development funds;and strengthening independent third-party supervision in the whole process of energy and mining development
