Den här studien undersöker kontinuiteten, vitaliteten, exponeringen och möjliga naturvårdsåtgärder i Solnas ekmiljöer. Enligt det 16:e miljökvalitetsmålet "ett rikt växt och djurliv" ska den biologiska mångfalden bevaras och nyttjas på ett hållbart sätt för nuvarande och framtida generationer. Gamla ekar har visat sig hysa en hög biologisk mångfald, men tyvärr minskar estånden av jätteträd kontinuerligt i Sverige samtidigt som föryngringen går långsamt eller i värsta fall helt avstannat. Åsikterna om jätteekarnas minskning verkar enstämmiga och bero på kontinuitetsglapp, upphörd hävd, igenväxning, plantering av gran på gamla odlingsmarker, brist på skötsel och ny bebyggelse i urbana miljöer. Kontinuiteten studerades genom att undersöka fördelningen mellan värdefulla ekar och ekefterträdare i hela Solnaområdet samt i fyra bestämda ektrakter. Kriteriet för god kontinuitet var 15 % värdefulla ekar och 85 % ekefterträdare. För att bedöma ekarnas vitalitet studerades andelen permanent döda grenar i trädkronan och för att bedöma ekarnas exponering struderades hur stor andel av trädkronan som täcktes av omgivande trädkronor. I varken hela Solnaområdet eller i trakterna observerades god ekkontinuitet. I hela Solnaområdet mår ekefterträdarna procentuellt sett sämre i samtliga vitalitetsklasser jämfört med de värefulla ekarna. För ekarnas exponeringstillstånd över hela Solnaområdet hade ekefterträdarna samma procentuella fördelning som de värdefulla ekarna när det gällde halvöppen exponering, men utöver det var ekefterträdarna jämförelsevis sämre exponerade. En viktig naturvårdsåtgärd för ekefterträdarna är att öka deras exponering, vilket kan göras med hjälp av frihuggning, slåtterhävd eller beteshävd.

Agricultural products are indispensable components of daily life. Nowadays, most cities in China, food supply is already setup, however the whole food supply chain is quite long with low efficiency. After the harvest of agricultural products, they have been transported to multi-hierarchical markets and go through plurality sales links by simple vehicles before meeting consumer. Due to the existence of an imperfect agricultural product supply system, specifically the inadequate infrastructure for cold-chain transportation and low-level storage technology, agricultural products and aquatic products, among others, suffer huge loss rates ranging from 15% to 30% during picking, transportation, and storage as well as during processing in other logistics sectors. Thus, some unscrupulous producers or agents add preservatives to the agricultural products in order to keep them looks with good quality. Besides, for the producers, though they do their utmost for farming and cultivating，they still living at the bottom of the social ladder with low income. For the consumer, owing to the increasing standard of living, the improvement of the logistical system and the structural adjustment of modern agricultural products, more and more consumers no longer just pursue the goal of having sufficient food to eat. Instead, they hope to eat better and healthier and prefer fresher or more diverse food options with high quality and nutrition. This thesis aims to study the existing agricultural product system in Guangzhou, focusing on the agricultural products supply model and discusses ways to revolutionize the “farm-to-table” agricultural products channel by proposing a new supply model in a regional scale to narrow the gap between consumer and producer in two main methods. On one hand, establish Agricultural Association to coordinate the whole system and guide the local farmer cultivate agricultural product and deliver their product to the consumer with high efficiency. On the other hand, attract the costumer come to productive area that they not only get the product directly but also understand the process of production. In these ways can guarantee the safety, freshness, and nutritional value of agricultural products, improve farmer’s income and satisfied consumer’s requirement by achieving a high-efficiency, low-pollution and energy-saving “farm-to-table” channel for local agricultural products. / published_or_final_version / Architecture / Master / Master of Landscape Architecture
