不拘于形，不役于物——欧阳修的园林活动与园林书写

欧阳修自幼与园林结缘，仕宦四十年，所到之处植花造园，笔耕不辍，留下数座园林景观、二十多篇园亭记及百余首园林诗词，撰写了现存最早的牡丹专著《洛阳牡丹记》，为后人研究园林提供了珍贵的史料。欧阳修的园林活 动和园林书写与其宦海沉浮、文学创作紧密相关。欧阳修热爱但不耽溺于园林，其崇尚自然、开放自适，不拘于形，不役于物的园林观，拓宽了园林审美的视域，启发了后人对“物”的审美思考，为园林理论注入了新鲜血液。欧阳修进一步打开了园林的大门，推动了园林的开放，为园林的繁荣与普及做出贡献。

新型蕨麻佐餐藏羊肉酱配方研究

以藏羊肉和蕨麻为主要原料进行新型复合型蕨麻佐餐藏羊肉酱的制作,在单因素试验基础上采用感官品评和正交试验分析,对复合酱配比、植物油添加量、藏羊肉添加量、蕨麻添加量以及复合酱添加量5个因素进行正交试验,依据感官评分表进行感官品评,确定蕨麻佐餐藏羊肉酱加工的最佳配方。结果表明,对蕨麻佐餐藏羊肉酱品质影响的因素依次为复合酱配比>复合酱添加量>植物油添加量>蕨麻添加量>藏羊肉添加量;并确定最终配方为植物油20.7%、羊肉17.2%、蕨麻3.4%、辣椒酱13.8%、甜面酱5.2%、花生酱5.2%、牛肉精膏0.3%、葱沫8.6%、蒜沫8.6%、盐1.0%、鸡精2.0%、味精1.7%、白糖3.1%、生姜粉0.3%、海天酱油3.1%、白芝麻1%、瓜子仁1%、辣椒粉3.4%。     

Measuring trail users’ perception of crowding in a peri-urban nature park: A best-worst scaling experiment

This paper evaluates the perception of crowding, its determinants and relationship with trail users’ experience in a peri-urban nature park. Existing crowding surveys rely heavily on a single-item 9-point crowding scale which was originally developed for backcountry areas. Receiver operating characteristic (ROC) analysis was used to test the validity and reliability of this measure in detecting crowding issues and formulating visitor capacity limits. Low validity and reliability raised concerns about the applicability of this scale in similar frontcountry areas. Inability of this simple crowding measure to detect a visitor threshold brings to the fore its another important limitation – ignorance of the complexity of crowding phenomenon. The perception of crowding varies with various social, psychological and situational factors, and a best-worst scaling (BWS) experiment was designed to simultaneously evaluate different aspects of crowding in the Medvednica Nature Park, a peri-urban nature park near Zagreb, Croatia. The findings of BWS experiment revealed that occupancy of mountain huts, number of other hikers on the trail and amount of litter along the trail on average contributed most to the trail users’ sense of crowding. A latent class analysis identified a large heterogeneity in the perception of crowding; while one group of trail users (63%) was more disturbed by the direct social impacts, the others (37%) were more disturbed by the secondary impacts of other visitors, especially by the negative externalities from road traffic in the park. Older visitors had a greater tendency to primarily associate crowding with the environmental conditions. A higher impact of trail use level in the perception of crowding, younger age and more frequent use were associated with a more negative evaluation of crowding. The park management should closely monitor road traffic in the park and visitor activity on highly used trails, especially on those popular among younger trail users.     

Influence of soil phosphorus status,texture, pH and metal content on the efficacy of amendments to pig slurry in reducing phosphorus losses

Cost‐effective strategies for using chemically amended organic fertilizers need to be developed to minimize nutrient losses in surface and groundwater. Coupling specific soil physical and chemical characteristics with amendment type could increase their effectiveness. This study investigated how water‐extractable phosphorus (P) was affected by chemical amendments added to pig slurry and how this effect varied with soil properties. A 3‐month incubation study was conducted on 18 different mineral soils, stored at 10 °C and 75% humidity and treated with unamended and amended slurry which was incorporated at a rate equivalent to 19 kg total P (TP )/ha. The amendments examined were commercial‐grade liquid alum, applied at a rate of 0.88:1 [Al:TP ], and commercial‐grade liquid poly‐aluminium chloride (PAC ), applied at a rate of 0.72:1 [Al:TP ]. These amendments were previously identified by the authors as being effective in reducing incidental losses of P. The efficacy of the amendments varied with the soil test P, the degree of P saturation (DPS ) and the Mehlich aluminium, iron and calcium, but not soil texture. Chemical amendments were most effective in soils with DPS over approximately 20%. Due to their high cost, the incorporation of amendments into existing management practices can only be justified as part of a holistic management plan where soils have high DPS .
