Problems solved by technology

First of all, large-scale logging often brings ecological impacts such as soil erosion and landscape changes. On the other hand, conventional afforestation techniques create a single forest stand species and forest structure, which is difficult to meet the purpose of tropical rainforest restoration.
[0004] At present, in the prior art, there is no report on the technology that successfully solves the above-mentioned problems through two strips of rubber plantations and two afforestations.

Embodiment 1

[0037] The afforestation method of rubber forest of the present invention restores and transforms tropical rainforest, and concrete steps are as follows:

[0038] 1. The first rubber forest felling and reforestation:

[0039] 1.1 The first felling of the rubber forest

[0040] Such as figure 1 As shown, for the rubber forests that need to be transformed in the project area, strip harvesting is carried out along the horizontal planting platform. Every 3 rows of rubber trees are kept, and 4 rows of rubber trees are harvested. The felling direction is upwards along the slope, and the height of the felling piles is strictly controlled within 5cm. Logging is carried out during the dry season to minimize disturbance to the soil and understory vegetation.

[0041] 1.2 The first rainforest restoration

[0042] Such as figure 1 As shown, in the year when the rubber forest was harvested, a natural recovery zone of about 12m wide was reserved in the lower part of the felling zone, a...

Embodiment 2

[0052] A 30-year-old rubber forest with an area of ​​500 mu in Jinghong City, Yunnan Province, the rubber forest land is 800-900m above sea level, the plant spacing is 2.5m, and the row spacing is 8m. In 2010, the technology of the present invention was used to restore the rainforest. According to the altitude range of the forest land, the target rainforest community designed for restoration is Parashorea chinensis--Pometia tomentosa forest.

[0053] In 2010, during the first felling of the rubber forest reconstruction, strip felling was carried out along the horizontal planting platform, and for every 4 rows of rubber trees felled, 3 rows of rubber trees were kept. The lower part of the logging zone is reserved for a natural recovery zone about 12 meters wide (1.5 times the rubber row spacing), and no forestation is made on it. In other parts of the logging zone, in June of that year, the dominant tree species (Wangtian tree and Longan tomentosa) and associated tree species (...

Embodiment 3

[0060] A piece of rubber forest at an altitude of 900-1000 meters in Xishuangbanna needs to be restored to a tropical rainforest. According to the altitude distribution of local zonal vegetation, the restoration will be carried out with the goal of tropical mountain rainforest. The target community is Parakmeria yunnanensis--Dacrycarpus imbricatus forest, and the afforestation tree species include dominant species: Pseudomonas yunnanensis and Pine pine; associated tree species are: Manglietia insignis, Engelhardtia spicata, Castanopsis argyrophylla and Schima wallichii; interlayer plants are: Smilax china, Smilax china, Melicopepteleifolia, Lasianthus hookeri, and Calamus henryanus. According to the method of the embodiment of the present invention 2, the rubber forest is felled twice and afforested twice, and finally a heterogeneous forest with multiple tree species and multi-source multi-layer structure is formed. Potential for natural restoration.

Abstract

The invention provides an afforestation method for restoring a tropical rainforest through rubber plantation. The afforestation method comprises two times of rubber plantation felling and two times of rainforest tree seed afforestation, the first time of strip-shaped rubber plantation felling is performed firstly to reserve a natural restoration belt, then the first time rainforest tree seed afforestation is performed in cutover land, the second time of rubber plantation felling is performed after 3 years, residual rubber trees are cut off, and then the second time of rainforest tree seed afforestation is performed. The sheltering conditions of young trees can be improved by using an afforestation technology, the survival rate of afforestation and the growth amount of the trees are improved, and an uneven aged mixed tiered forest rich in structure is formed. By the adoption of the felling and afforestation method, the water and soil loss of the new afforestation land can be effectively reduced, the influence of felling on a landscape can be reduced, and the ecological impact brought by large-scale rubber plantation felling can be controlled. The afforestation method for restoring the tropical rainforest through rubber plantation has the advantages of being rapid in artificial community growth, good in stand structure and small in environmental ecology impact and can achieve a good rainforest restoring effect.

Description

technical field [0001] The invention belongs to the technical field of forest cultivation and application, and in particular relates to an afforestation method for large-scale rubber (Heveabrasiliensis) forest transformation and restoration of tropical rainforests, and more specifically, relates to an afforestation technology for rubber forest felling and tropical rainforest artificial ecological community reconstruction . Background technique [0002] There are large areas of rubber forests planted in the tropical regions of my country, and most of the zonal natural vegetation in these rubber forest distribution areas is tropical rainforest. As the country and society have higher and higher requirements for ecological protection, the restoration and transformation of some rubber forests that have important restoration value and have restoration conditions have become a major forest cultivation and ecological restoration technical issue. [0003] my country's rubber plantin...
