Paper plantations benefit poor mountainous areas in Yunnan in mid July 2006, the author participated in the "green Yunnan trip" activity sponsored by green China magazine and went to Yunnan to investigate plantations. During the week-long activity, I traveled to Kunming, Simao, Lancang and Jinghong counties and cities in Yunnan Province. Together with my classmates from Renmin University and Communication University, I visited a large area of plantation bases, listened to reports on plantation, and interviewed forest researchers. The schedule is very tight, and the author is not an expert. He cannot make a profound conclusion about the advantages and disadvantages of artificial forests in Yunnan. He can only use what he saw and heard along the way to get his feelings, which can also be regarded as a record of his trip to Yunnan. During the Tenth Five Year Plan period, Yunnan Province increased the forest area by 40.2276 million mu, and the forest coverage rate reached 49.91%. On this trip, our first destination is Simao, which has a forest coverage of 64.9%, and is known as the "Pearl of the green sea" in Yunnan. The Eucalyptus introduction test base, Moshi afforestation base and nursery visited later were in Lancang Lahu Autonomous County of Simao. Eucalyptus introduction test base was built by Lancang forestry bureau since 1992 last century. The original intention is to solve the urgent problems of forestry development and ecosystem reconstruction due to the local barren mountains and barren forests. Mojie afforestation base and nursery are the afforestation projects of APP in Sancun village, Huixiang Township, East Lancang. The former has a forestation area of 7937.9 million. In the first two months of 19, the fixed asset investment in the paper industry decreased by 5.6% 6 Mu year-on-year, and has been planted since the middle of 2004. The latter covers an area of 900 mu, which is used to provide seedlings for the construction of the former forest land. It was also put into production in 2004. When we approached the forest area of the base, the green scenery we saw was small and successful. The trees in the test base are already lush, and the top can be seen only when you look up to 90 degrees, which is worthy of "time-honored brands"; The trees in the afforestation base are planted in three batches. Since 2004, they have been planted every year, from far to near, with clear layers. It is said that eucalyptus trees become forest in one year and timber in threeorfour years. At this time, they are three generations of "strong, young and young". According to caozhongfu, deputy director of Lancang County Forestry Bureau, in 2004, there were 700000 mu of barren mountains in the county, but only 320000 Mu are left at present, and the forest coverage rate of the county has also reached 59%. Afforestation is a national policy that three generations of leaders attach great importance to. It is reported that during the "Tenth Five Year Plan" period, of the more than 40 million mu of forests newly added in Yunnan Province, 1989.47 million mu of artificial forests. We can see the importance of plantation in green work in Yunnan
on a hill of the test base, But research at the University of Texas in Austin also focused on graphene composites, said Rodney ruoff "The author reported that the organizer asked the students to divide into two groups for the plant specimen collection competition. The competition results showed that the largest group collected 32 species, and the other group also had more than 20 species. The introduction test of eucalyptus has been carried out in this base since 1992. More than a decade later, the diversity of the ecosystem is still maintained at a certain level, and the density of vegetation under the tree can reach the level that people can't see the topsoil directly. Li Kaijie, the R & D director of Moshi afforestation base Shao, they conduct soil analysis on the forest land once a year, collecting and analyzing more than 300 soil samples in order to put forward the next fertilization plan. The R & D period is 6 years, and the fertilizer is changed three times. The measurement and frequency of fertilization are controlled within the range that the natural environment can bear. They advocated mixed cultivation in artificial forest areas, such as mixed winter melon, to avoid the single biological variety. Therefore, the forest land has not caused ecological damage or vegetation reduction due to the entry of Artificial Eucalyptus
on the way from Simao airport to Lancang County, I passed a bridge, under which is a tributary of Lancang River. According to the guide, Nuozhadu Hydropower Station, a national hydropower station under construction, is nearby. When I got off the bridge to visit, I was surprised to see the yellow water rolling under the bridge. Looking at the scenery on both sides of the river, it was already bare earth. At the "Fourth China International NGO Cooperation Forum" held at the end of last year, Professor Yang Suhua of Yunnan University stressed in his keynote speech "strategic significance of biodiversity conservation" that attention should be paid to the problem of soil erosion in Yunnan
Lancang County we visited this time is the only Lahu Autonomous County in China. We came to Banli village, Donghui Township, Lancang County, which has one of the ownership of the afforestation base. The casual modern atmosphere in the village can also brighten people's eyes from time to time and feel the development of the village. Look at the "village to village" pot and the bamboo building on the pile live in harmony, and listen to Lahu folk songs with modern guitars. Originally, for this village, which is located in deep mountains, has little mineral resources, and is still lingering in the inefficient agricultural operations of slash and burn farming, it can only wait for the country to help the poor if it wants to develop. But now we know that the main benefit of farmers in the promotion of artificial forests lies in labor fees. In 2004, the labor expenditure for plantation in the single mill medium afforestation base was 600000 yuan, and in 2005 it was 700000 yuan. According to the data provided by Mr. zhangronggui of the Research Institute of Yunnan Academy of forestry, in 2004, 23 townships in Lancang County, Simao, Yunnan Province built high-yield eucalyptus forests, and farmers received a labor income of 70.43 million yuan, with an increase of 163 yuan per capita. This is a good start for the poor mountain villages that used to generate little income. Under the guidance of professional forest researchers, planned and scientific afforestation and cultivation have turned the previous "relying on mountains and forests to feed on forests" into "cultivating forests with mountains, supporting people with forests, and protecting mountains with people"
the mountainous area of Yunnan is 94%, and the sparse forest land, shrub forest land and immature forest land account for 20.66% of the forestry land, most of which are inefficient forests that need to be transformed. If this situation is left unchanged, it will only worsen the situation; It is also unrealistic to wait for the country to invest in transformation and turn it into an industrial forest for decades. To make effective changes, we should focus on the introduction of non-public sectors and develop planted forests in a planned way. Only when departments at all levels take the right direction and make good use of external forces can we effectively improve the backward situation
78% of the population in Yunnan is rural, including 30.96% of the poor. Under the overall requirements of the new countryside, science Reasonable plantation is a feasible way for Yunnan to achieve the sustainable development goal of invigorating the economy and improving farmers' lives under the premise of protecting the environment
