在我国乡镇企业发达的乡村地区,由于产业结构的调整和农业的自我服务化,形成了三种选择机制,影响农业区位,使自然地理过渡带优势逐步丧失,农业区位转移,农业区位质量也下降。建议制定宏观农业区位政策。  相似文献

居民日常的膳食消费与水资源的保护和节约息息相关。根据吉林省1999—2011年城乡居民膳食消费量,量化城乡居民膳食水足迹,并分析其特征。13年来吉林省城乡居民膳食水足迹波动不大,但城乡之间存在差异。城镇居民膳食水足迹中肉类所占比重最大,而农村居民膳食水足迹中粮食占绝对比重。城镇居民膳食水足迹多样性指数高于农村居民,均呈上升趋势,尤其是农村居民膳食消费的种类增长较快,居民膳食消费的种类日益丰富。吉林省城乡居民膳食水足迹虽然存在差异,但差距不大,不公平现象不明显。  相似文献

A sediment budget is constructed for the South Saugeen River, a sixth-order stream basin in southwestern Ontario. Input from eroding glacial embankments accounts for up to 68% of the fine (<63 μm) sediment outputs from the basin. Sediment derived from eroding alluvial banks in the main river contributes approximately 22% of sediment outputs and is approximately equivalent in magnitude to sediments stored in the floodplain. The remaining 10% is derived from sheet and rill erosion of uplands that have been modified by agriculture. However, specification of an appropriate sediment delivery ratio from individual fields to the low-order tributaries remains problematic. Small reservoirs confined by mill dams constructed around the time of land settlement in 1860 store about 3% of the basin sediment inputs. The results demonstrate the importance of downstream, non-alluvial (glacial) sediment sources and can be linked to the model of increasing specific sediment yields with drainage area found in several other river systems of Canada. The high frequency of tall glacial banks in several entrenched river valleys entering the Great Lakes in southern Ontario indicates that the model of dominantly agricultural sediment inputs needs to be adjusted for this region.

Government units such as counties and cities have long been the basis for economic development, service delivery, and problem solving in rural America, but they are increasingly inappropriate, because many of them are too small to reach the critical mass and because rural issues often transcend arbitrarily set political boundaries. To overcome the resultant adverse effects, many rural communities have been rethinking their development strategies and actively forging regional partnerships. Ad hoc regionalism is a politically feasible and effective way for rural communities to collaborate in these initiatives. The exact issues that spark such collaboration may vary from place to place, but they are all grassroots, voluntary regional governance frameworks or innovations. They allow rural communities to pool their resources and reach the critical mass necessary to tackle a variety of regional issues and take advantage of new economic development opportunities without replacing or threatening existing government units. The two case studies discussed in this article—the western Kansas Rural Economic Development Alliance and the San Juan Forum in the Four Corners region of the southwestern United States—show that ad hoc regionalism offers several advantages over rural communities working independently but that challenges in implementing it exist.  相似文献

目前,乡村旅游得到了前所未有的发展,但其主要集中在经济发达城市的周边地区。该文旨在探讨象张家界这样不具备区位优势的中小型专业化旅游城市,如何发展独具特色的乡村旅游,并给出了一个参考思路,即依靠传统观光型旅游的带动。在这一思路指导下,对张家界的乡村旅游发展进行SWOT分析,提出了乡村旅游开发的宏观和微观建议。  相似文献

腾冲旅游开发对农村发展的影响初探   总被引:1,自引:0,他引:1  
用腾冲县1997~2003年的社会经济发展统计资料和旅游景点所在乡、村的农民收入与就业的调查资料,分析了腾冲旅游总收入、游客人次对县域经济、农业产值、农民收入与就业的影响。腾冲旅游开发对腾冲县3次产业结构调整发挥了关键作用,加速了第三产业的发展,分析年份中旅游总收入平均增幅达35.05%,占国内生产总值比重平均达14.6%,占第三产业比重平均达34.42%。但是,农业生产总产值、农民人均年纯收入与旅游总收入、国内游客人次呈负相关。旅游业给景区农民增加了新的收入渠道,但旅游景区内农村人均年收入并不比全县其它地区高。旅游业用地征自于农民耕地,但景区农民收入并未得到与旅游业同步的增幅。旅游开发对“三农”发展的带动力没有得到充分的发挥,应进一步完善旅游可持续发展与“三农”发展的协调。  相似文献
