近日，6吨锦屏山牌水蜜桃从浙江奉化溪口镇启运，发往温州世纪联华超市。此前，奉化市政府在温州举行水蜜桃市场推介会时，溪口镇政府与温州世纪联华超市签订了长期代销协议，奉化水蜜桃在该超市试销近1个月，是该超市销量最好的水果之一，销量已从开始时的每天1000千克增加到现在的6000千克。同一天，奉化的溪口、萧王庙、锦屏三大主产桃区每天有20吨奉化水蜜桃供应省内外10余家超市。 相似文献

Conflicts among forest visitors have direct effects on the quality of a recreational experience. As the number of visitors to forests close to residential areas increases, as well as the number of different activities, so does the potential for perceived conflicts. According to the literature, expanding knowledge of conflict characteristics and their causes is important for recreation planners and managers who aim to reduce conflicts.In the present study, different forest user groups were identified and categorised according to their pursued activities, and for each group, causes of conflict were identified. Furthermore, a choice experiment was constructed to estimate the distance visitors are willing to travel to encounter few visitors as opposed to many visitors, and thereby potentially experience fewer conflicts. Comparing the marginal willingness to travel (WTT) of different user groups suggests that some groups have a WTT further than the average to reach a forest with ‘Few’ visitors. The average WTT to reach a forest area with ‘Few’ visitors. ‘Mountain bikers,’ ‘Peace and nature lovers’ and ‘Horse riders’ are willing to travel 4 km more than the average per visit to reach a less crowded forest. At the other end of the scale, we find that people who are doing physical exercise are willing to travel 2 km less than the average to reach a less crowded forest. 相似文献

桃砧木筑波4号和筑波5号抗根癌病鉴定评价 总被引：2，自引：0，他引：2
以当年实生筑波4号(Prunus persica‘tsukuba-4’)和筑波5号(Prunus persica‘tsuku-ba-5’)的新梢为材料,采用人工接种发根土壤杆菌(Agrobacterium rhizogenes)的方法研究了其对根癌病的抗性及其分离情况。结果表明,筑波4号实生群体中免疫、高度抗病、中度抗病、中度感病和高度感病类型分别占0.90%、1.80%、9.01%、18.92%和69.37%。筑波5号实生群体中免疫、高度抗病、中度抗病、中度感病和高度感病类型分别占1.01%、3.03%、8.08%、38.38%和49.49%。筑波4号和筑波5号对发根土壤杆菌的抗性存在显著分离现象,可从中筛选出抗性极强的植株。 相似文献

Biogeochemical models offer an important means of understanding carbon dynamics, but the computational complexity of many
models means that modeling all grid cells on a large landscape is computationally burdensome. Because most biogeochemical
models ignore adjacency effects between cells, however, a more efficient approach is possible. Recognizing that spatial variation
in model outputs is solely a function of spatial variation in input driver variables such as climate, we developed a method
to sample the model outputs in input variable space rather than geographic space, and to then use simple interpolation in
input variable space to estimate values for the remainder of the landscape. We tested the method in a 100 km×260 km area of
western Oregon, U.S.A. , comparing interpolated maps of net primary production (NPP) and net ecosystem production (NEP) with
maps from an exhaustive, wall-to-wall run of the model. The interpolation method can match spatial patterns of model behavior
well (correlations>0.8) using samples of only 5 t o 15% of the landscape. Compression of temporal variation in input drivers
is a key step in the process, with choice of input variables for compression largely determining the upper bounds on the degree
of match between interpolated and original maps. The method is applicable to any model that does not consider adjacency effects,
and could free up computational expense for a variety of other computational burdens, including spatial sensitivity analyses,
alternative scenario testing, or finer grain-size mapping. 相似文献
