Accessing research sites is an integral part of a research in the world today. Researching sites on privately owned lands creates unique challenges when compared to conducting research on government or publicly owned land. This study explores different methods for obtaining landowner information, permission to sample privately owned sites, and assesses the time it takes to obtain permission for randomly selected study sites. During the study, researchers contacted 390 landowners to obtain permission to sample wetlands on privately owned lands. A variety of methods were used to contact landowners and determine which methods were most effective for obtaining permission. Methods included face-to-face discussion, phone calls, and mailed response letters. It took approximately 9 months to obtain landowner information, contact landowners, and obtain permission to sample sites. The most effective method for obtaining permission to sample sites was through face-to-face discussions with landowners. Overall, it took a longer period of time to obtain permission for the survey than it did to sample sites. Information from this study can be used by anyone conducting research on private land to better estimate the time it will take to obtain permission to sample sites and to estimate the most effective way to obtain permission based on project finances and available personnel.  相似文献

围栏封育在伊犁昭苏盆地退化草地生态恢复中的应用   总被引:7,自引:0,他引:7  
闫虎  沈浩 《干旱环境监测》2005,19(2):102-103,110
目前新疆伊犁地区草地退化、生态环境恶化,严重影响到伊犁州区域的经济发展和生态安全。本文以伊犁昭苏盆地昭苏马场春秋草场围栏封育区为研究区,定量分析围栏封育技术对退化草场恢复作用及其机制,以期发现恢复程度与封育时间的相关关系。结果得出围栏封育后优良牧草增产幅度大,两年围栏分别比一年围栏和不围栏增产262.95kg/hm^2和7723.5kg/hm^2。围栏封育两年后的草地适做放牧利用,而围栏封育一年适做打草场利用。  相似文献

Policy concerns related to the environment have grown in the past decadesfrom relatively local and well-defined problems to increasingly complex andglobal issues. With this has grown the need to develop the capacity tointegrate, reconcile, organize, and communicate knowledge across scientificdisciplines, as well as to make this knowledge available and useful for policy-makers. One response to this has been the growing field ofIntegrated Assessment (IA). Our goal in this paper is to reflect on the purpose and valueof IA in principle. We propose a conceptual framework within whichindividual IA studies, and the practice of IA as a whole, can be placed andevaluated. The framework addresses both the integrative nature of IAs andtheir policy usefulness, including a self-awareness of their role and capabilities. We illustrate several stages in the evolution of integrated assessments: fromlinear to more complex chains of analysis, from non-adaptive to perfectly-adaptive to realistically-adaptive agents, from simplistic to sophisticated to pluralistic consideration of alternative underlying development paths, from strictly quantitative to quantitative and qualitative analyses, from science-driven to policy-driven, and from analyses that dictate to users to those that involvethose users in the actual assessment process. By so doing, we argue for botha richer form and process of IA. Ultimately, we feel that it may also benecessary to reconsider the framing of the questions that IAs have been askedto address, perhaps leading to the consideration of the use of other forms of mandated science.  相似文献

Sensitivity analysis is becoming increasingly widespread in many fields of engineering and sciences and has become a necessary step to verify the feasibility and reliability of a model or a method. The sensitivity of the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method in water quality assessment mainly includes sensitivity to the parameter weights and sensitivity to the index input data. In the present study, the sensitivity of TOPSIS to the parameter weights was discussed in detail. The present study assumed the original parameter weights to be equal to each other, and then each weight was changed separately to see how the assessment results would be affected. Fourteen schemes were designed to investigate the sensitivity to the variation of each weight. The variation ranges that keep the assessment results unchangeable were also derived theoretically. The results show that the final assessment results will change when the weights increase or decrease by ±20 to ±50 %. The feedback of different samples to the variation of a given weight is different, and the feedback of a given sample to the variation of different weights is also different. The final assessment results can keep relatively stable when a given weight is disturbed as long as the initial variation ratios meet one of the eight derived requirements.  相似文献
