摘要:
【目的】在林业经营中优化利用已有的生产要素(包括林地、技术、劳动力、资金),实现林业生态绩效增长。【方法】将林木“轮伐期”作为生产要素投入与林业生态绩效增长的中间变量,分析生产要素优化对林业生态绩效增长的作用机理,并以福建省沙县林业生产为例进行实证研究。【结果】人工经营林地的生态绩效与生产要素投入关系为:生产要素优化可提高林业生态绩效,如国有林场因林地经营面积大、资金成本较低且营林技术更先进,其生态绩效好于其他经营方式的林地; 生态绩效与林地经营规模间存在“门槛”效应,当林地经营面积超过“门槛”规模后,林木轮伐期才可能延长并进一步提高生态绩效。不同林业经营方式其生产要素优化面临不同问题:国有林场需更多林地投入以应对用材林林地减少而年度用材林采伐量却增加的困境; 村集体林场面临林地与资本短缺; 经营型小农户面临技术、资本与劳动力投入的全面短缺。【结论】生态绩效增长的关键在于林地收益最大化前提下的林木轮伐期延长,而轮伐期延长可通过采用更先进生产技术(按高标准森林经营技术规程进行营造林)、投入更多资本且降低资金成本、投入更多林地等要素优化路径实现,其中林地经营面积大于“门槛”规模是轮伐期延长的必要条件。
Abstract:
【Objective】Increase the forest ecological performance through optimizing the forestry production factors, which include forest land, technology, labor and capital. 【Method】The mechanism of factor optimization on the growth of ecological performance of forests was analyzed using forest rotation as the intermediate variable between factor input and growth in ecological performance; a case was studied in Shaxian County, Fujian Province. 【Result】 ① The relationship between the ecological performance and factor input of forest land with operation is as follows: first, the optimization of production factors can improve ecological performance, e.g., state-owned forests have better ecological performance than other types of forests because of large forest lands, low capital costs, and advanced forest operation technologies. Second, there is a “threshold” effect between forest management scale and ecological performance. When the forest land area exceeds the “threshold”, it is possible to extend the forest rotation age and further improve the ecological performance. ② All forest production factor input modes should be optimized: state-owned forest farms need more forestland input, collective forest farms face forestland and capital shortage, the villagers' group and household management are faced with the comprehensive shortage of technology, capital, and labor input.【Conclusion】The key to forest ecological growth is to extend forest rotation under the rule of maximizing forest revenue, and the factor input needs to be optimized as follows. First, adopting advanced production technology, i.e., land preparation and thinning according to the high standard forest management technical regulations, adopting good seeds and strong steckling, and investing in more fertilizers and other land saving technologies. Second, reducing capital costs and investing more capital. Third, more forest land input to cope with the increased demand for forest land management due to the extension of forest rotation period. Finally, the forest “threshold” scale is necessary for the extension of forest rotation period.
