Abstract

Forests play an important role in water conservation. It is important to study the relationship between forest water conservation (FWC) and forestry investment. Based on official statistics and ecological network observation data in China from 1999 to 2013, this paper for the first time uses correlation analysis and regression analysis methods to analyze the relationship between FWC and forest silviculture investment in fixed assets (FSIFA). Results show that FWC and FSIFA have a strong correlation and a strong influence, correlation coefficient is around 0.96. The amount of annual forest water conservation is increased with an increase in investment in fixed assets. The study also found that FSIFA affecting annual FWC lags more than 1 year, showing that FSIFA cannot play a role in water conservation immediately. The research also discussed other affecting factors on FWC, such as forest coverage rate, economic development level and forest quality improvement, etc. Their effects were also found to lag 1–5 years. Finally, the paper predicts the amount of annual FWC from 2014 to 2020 and gives some suggestions to strengthen investment in forest fixed assets and improve management of forest resources so as to promote the development of benefits of FWC.
中国造林固定资产投资对森林保水的影响
森林在水源保护方面发挥着重要作用。研究森林水利与林业投资的关系具有重要意义。基于1999~2013年中国官方统计数据和生态网络观测数据,本文首次采用相关分析和回归分析方法,分析了FWC与森林造林固定资产投资(FSIFA)的关系。结果表明,FWC和FSIFA具有较强的相关性和影响,相关系数约为0.96。随着固定资产投资的增加,每年的森林节水量也在增加。研究还发现,影响年度FWC的FSIFA滞后1年以上,表明FSIFA不能立即在节水方面发挥作用。研究还讨论了影响FWC的其他因素,如森林覆盖率、经济发展水平和森林质量改善等。它们的影响也滞后1-5年。最后,预测了2014年至2020年全年森林固定资产的总量,并提出了加强森林固定资产投资和改善森林资源管理的建议,以促进森林固定资产效益的发展。
