东海陆架盆地及其周边海域地质、地球物理场特征

分东海陆架盆地及其周边海域的重、磁场特征、对研究区域的地球物理场资料进行了小波变换与多尺度分布与计算，计算了研究了海域重，磁资料的1－4阶小波变换逼近、细节、根据分析与计算可知，在东海陆架盆地及其周边域，重、磁异常的主要特征没有内陆盆地那样明显，但盆地内的绝大部分地区均位于异常相对缓变区，在盆地内部有时有局部异常的圈闭及剧变区，但总的特征为缓变的，而周边区域多为相对剧变区，但也存在局部区域的缓变, 、磁场特征表明，盆地基底相对盆地周边区域主要由密度较大，磁性中的岩石组成，因此盆地中部以高正磁异常为主，布格重力异常 对周边地区高，东海陆架盆地及其周边海域的重力场的主要走向为NNE向，局部重力异常较为平缓，磁异常走向没有重力异常明显，但主要也为NNE向，重、磁场的分布特征表明，东海陆架盆地及其邻域的地质构造为大陆架构造的延伸。     

Mapping Farmer Identity: why,how, and what does it tell us?

Rural areas in developed economies are becoming increasingly multi-functional in that their character is being shaped by a mix of production, consumption and conservation values. Agriculture may remain the dominant land use, but many landholders do not see themselves as farmers by occupation. Researchers have demonstrated that occupational identity influences land use and management. However, efforts to explore the influence of occupational identity often rely on surrogate measures and have largely ignored identity theory. We build on research demonstrating that collective identity theory can be used to develop a valid and reliable measure of farmer identity and to then classify rural landholders across a natural resource management (NRM) region. The contribution of this paper is to explain how that measure of farmer identity can be mapped and then demonstrate the relevance of doing so for regional NRM in Australia. As expected, farmer identity varied across the case study region with distance from urban centres, and across different environmental assets. Those findings should lead to a more targeted approach to landholder engagement in NRM. We suggest that farmer identity (i.e. farmer-collective occupational identity construct; F-COIC) might provide a next step for responding to the challenges of interpreting and mapping multi-functionality.     

A story of “communities”: boundaries,geographical composition and social coherence in a forest conservation project,Northern Cambodia

Explicit notions of “communities”, as key actors in conservation and development projects across the Global South, are common. Narratives about “indigenous people” or “forest-dependent communities” in forest conservation programmes prevail, portraying a picture of “communities” as homogeneous and harmonious entities. In this study, we unfold “communities” as a construct with an empirical example of a community-based forest protection project, Northern Cambodia. Based on qualitative interviews, field observations and document analysis, we examine the “community” construct in terms of establishment of boundaries, geographical composition and social coherence. We not only find that the establishment of forest “community” boundaries are dominated by powerful external actors rather than the “community members” themselves, but that the spatial composition of “communities” is complex, and affects the ability of local people to benefit from the project. We also find that the studied “communities” show low levels of social coherence and mainly consist of migrant farmers, as opposed to common policy narratives. Taking these inconsistencies into account, we discuss implications of constructing “communities” for the success of forest conservation projects, and argue in favour of more discursive and political analyses to better understand, acknowledge and adapt to existing and changing conditions in present and prospective project locations.
