摘 要
我国南方地区以其独特的气候条件和丰富的自然资源，成为经济林种植的重要区域。经济林作为农业经济的重要组成部分，不仅为农民提供了重要的经济来源，还促进了农村地区的可持续发展。然而，近年来，随着气候变化和生态环境的不断变化，南方地区经济林病虫害问题日益凸显，成为制约经济林产业健康发展的关键因素。病虫害的频繁发生不仅导致经济林产量下降、品质受损，还增加了农民的经济负担，影响了农村经济的稳定增长。因此，本文旨在探讨我国南方地区经济林病虫害的现状、问题及对策。首先，分析了南方地区经济林病虫害的种类、分布特点及其对经济林生长和产量的影响。随后，从防治措施实施、经济林管理模式及农户防治意识与行为等方面，深入剖析了当前存在的问题。针对这些问题，本文提出了引入与培育抗病虫害品种、加强病虫害监测与预警系统、推广科学防治技术、优化与执行防治政策、创新经济林管理模式、引入现代化管理技术与设备以及提升农户病虫害防治知识等具体对策。通过实施这些对策，旨在有效降低病虫害的发生和危害，保障经济林的健康生长，提高经济效益和生态效益。

Abstract
With its unique climate conditions and rich natural resources, the southern part of China has become an important area for economic forest planting. As an important part of agricultural economy, economic forest not only provides an important economic source for farmers, but also promotes the sustainable development of rural areas. However, in recent years, with the continuous change of climate change and ecological environment, the problem of diseases and insect pests of economic forest in southern China has become increasingly prominent, which has become a key factor restricting the healthy development of economic forest industry. The frequent occurrence of diseases and insect pests not only leads to the decline of economic forest yield and the damage of quality, but also increases the economic burden of farmers and affects the stable growth of rural economy. Therefore, this paper aims to explore the current situation, problems and countermeasures of economic forest diseases and insect pests in southern China. Firstly, the types and distribution characteristics of diseases and insect pests on the growth and yield of economic forests in southern China are analyzed. Then, from the implementation of prevention and control measures, the management mode of economic forest, and farmers' awareness and behavior, the current problems are deeply analyzed. In view of these problems, this paper puts forward specific countermeasures such as introducing and cultivating varieties against diseases and pest, strengthening the monitoring and early warning system of diseases and insect pests, popularizing scientific control technology, optimizing and implementing control policies, innovating economic forest management mode, introducing modern management technology and equipment, and improving the knowledge of farmers' diseases and pest control. Through the implementation of these countermeasures, it aims to effectively reduce the occurrence and harm of diseases and insect pests, ensure the healthy growth of economic forest, and improve the economic and ecological benefits.
