摘要：The aim of this study is to find an optimal design for a distributed hybrid renewable energy system(HRES) for a residential house in the UK. The hybrid system, which consists of wind turbines, PV arrays, a biodiesel generator, batteries and converters, is designed to meet the known dynamic electrical load of the house and make use of renewable energy resources available locally. Hybrid Optimization Model for Electric Renewables(HOMER) software is used for this study. Different combinations of wind turbines, PV arrays, a biodiesel generator and batteries are evaluated and compared using the NPC(Net Present Cost) method to find the optimal solutions. The HRES is modeled, simulated and optimized using HOMER. The results showed that the wind-biodiesel engine-battery system was the best with the lowest NPC(USD 60254) and the lowest COE(Cost of Energy, USD 0.548/k Wh) while the second best system added PV arrays. This study gives evidence of the key contribution wind turbines make to HRES due to abundant wind resources in the UK, especially in Wales.

摘要：以近自然森林经营理论为依据,拟在春城面山选取1.33hm 2华山松林,通过清除华山松病害木、带状间伐等措施后,在间伐带内培育云南高原特色乡土树种,如云南含笑、云南厚皮香、云南山茶、白花油茶、红花油茶、马樱花、滇润楠、红枫等树种。同时对项目研究区的水、电、路、房等设施和林木种苗信息市场进行调查,作出云南高原特色乡土树培育可行性研究,供林草同行参考。

摘要：通过调查滇中珍贵野生植物资源分布概况,精选西康玉兰、龙棕、黄杉、马樱花、云南含笑、云南厚皮香、滇润楠、西南栒子等野生物种,选择海拔高度、气候条件、土壤类型相近,交通水电便利的区域,用有性繁殖方式培育上述物种,以达到种群数量增加,生物多样性保护功能增强的目的。有效提升滇中生态环境质量,促进生态文明建设,为林区振兴和乡村振兴服务,助力“美丽滇中”建设。

摘要：基于对洱海水生植物群落的调查,洱海共有16个水生植物群落,也查清了云南高原湖泊洱海水生植物的资源情况,通过对植物群落的分析研究,讨论研究的结论对湿地公园的建设与管理具有指导和现实意义。

摘要：文章以昆明金殿国家森林公园局部绿地为例,调查分析红火蚁生活环境和蚁巢分布现状,并对绿地内分布的红火蚁进行防治,效果显著。将防控成效与同行分享,供绿地红火蚁防治参考。

摘要：以云南高原特色乡土树种华山松幼林为研究对象,实地调查华山松幼林的地径、苗高、冠幅等测树因子,运用统计学原理分析各区组地径、苗高和树冠的生长态势,并用方差分析方法,检验分析其显著性,对后续华山松单株先优和林分高效培育提供科学依据。
