Establishment of nature reserves may however generate constraints for development of local communities residing in these reserves. The village ecosystem of Zhuanjinglou Village in Wolong Nature Reserve includes population, farming and livestock (domestic and alpine) and forest ecosystem. An emergy analysis of agro-ecosystem (including the farming and livestock ecosystem) and energy consumption in Zhuanjinglou Village indicates that livestock ecosystem plays an important role in village ecosystem, which may be the source of great pressure on the state of the local environment. The increasing ratio of electricity in energy consumption may play a positive role for environmental conservation. Despite some successful experiences, there are some remaining issues that need to be addressed in the ecological rehabilitation of the village ecosystem.展开更多

These surveys showed that up to 20 families and 45 species of WMP were harvested in WNNR. Gastrodia elata, Paris polyphylla, Fritillaria thun-bergli, Rheum officinale, Rhodiola rosea, Saussurea medusa, Notopterygium root, Radix Ginseng, Buddha＇s palm were harvested intensely. The harvesting, which occurred mainly in autumn and winter （from June to October） in the test area, buffer area and core area, was located mostly in the residential and crop production areas of Wolong Town and Gengda Town, and in the timberline, alpine meadows and scree areas of Dengshenggou Ravine and Balangshan Mountain （specifically in Dengshenggou, Tangfang, Tizigou Ravine, Wei- jiagou Ravine and Reshuihe River areas）. Among all the harvesters, 58% came from inside the WNNR, and 42% came from outside the WNNR; 87% were male, and 13% were female; 6% were under the age of 18, 69% were 19-45 years old, 19% were 46-65 years old, 6% were over 66 years old. The main purpose of harvesting was commercial sale to increase household income. Based on the analysis and discussion of the results, comprehensive management measures were introduced to strengthen the awareness and efficacy of laws and regulations, integrate the enforcement of these laws, establish and strengthen inspections. Skills training and the domestication of the wild medicinal materials were used to encourage the surplus labor force to avoid excessive harvesting and move into other agricultural endeavors.展开更多
