(2) Analysis of agricultural production impact

The airport project will occupy cultivated land of 23.9333hm² (including paddy field of 17.8689hm², dry land of 6.0644hm², not taking up basic farm ), occupy the 1.1378hm² (orchard of 0.1443hm², tea garden of 0.9935hm²), the airport road project land of 27.8hm², cultivated land of 6.98hm², field of 0.002hm², farmland of 1.32 hm². Engineering construction will have impact on agricultural ecological system in the following areas:

① Changes in soil properties

Construction on farmland ecological environment influence is mainly covers will make farmland soil properties changed by comparison, fertile soil, suitable for crop growth, change of the concrete structure is not suitable for crop growth, poor permeability structure, reducing soil natural productive force. Therefore, the airport under construction should be farmland area of about 30cm thick upper soil layer to peel, temporary accumulation of stored, take effective measures for soil and water conservation, green for airport, also can be timely removed for urban greening or land reclamation. Never casually discard it into the pit.

② Effects on crops and fruit trees production

Airport construction will take up farmland 32.4333hm^2, among them paddy field area is 17.8689hm², 14.3644hm2. The region includes dry land, crops to rice, cotton, sweet potato, taro, peanut and so on. Construction period all construction sites will destroy the original farmland, make area crop yield reduction of 293.2861t/a.

In addition, airport construction will commandeer garden area of 1.1398hm². according to the average yield of 55t/hm² project area of fruit trees, tea yield average 40t/hm² calculation of the project occupies garden will make biomass yield reduction of 47.6765t/a.

In the process of construction, transport vehicles, construction machinery and personnel will be on the adjacent farmland interference, construction site and soil loss water may enter the field, affecting the normal agricultural production.

(3) Analysis of influence on forestry resources

Forest land are the important natural resources and strategic resources, forest survival and development foundation, is non-renewable resources. Construction of forest land requisition and occupation in pine, slash pine, Sugiki, broad-leaved tree (camphor tree). The project will lead to regional forest resources decrease of 108.1356 hectares, the area of masson pine, Sugiki, slash pine processing products and Camellia edible oil products supply capacity with the forest land resources reduction. Thus, the construction unit and the local government should timely implementation of compensation funds, and guide farmers to forest vegetation remote recovery, reduce project construction of commodity forest resource, forest products supply capacity and farmers' revenue.

(4) Protect the plants and trees effect

Through on-site inspection, project use forest land is distributed with the state protection of two species of camphor tree, by sampling measurement, distribution of 3,722 strains of Cinnamomum camphora, will be composed of land units employ a quality, strong technical force units responsible for transplant processing, where the township forestry and Forestry workstation is responsible for the supervision and technical guidance for transplant, Shangrao County and Xinzhou forestry management.

Transplant locations proposed location in short distance, with corresponding scale, have the ability to receive the number of nursery. Camphor tree transplant is nearly not far away, so transplant location principle of distance camphor tree original grow closer, if make sure transplant after the nursery and growth in the same spatial geographical unit, climate, soil, illumination, moisture and other similar environmental conditions, at the same time with the artificial careful conservation, camphor tree transplant in ecological suitability angle is feasible.

4.2.1.3 Analysis of animal impact

(1) Influence on Amphibians

The region accounted for amphibian animal mainly for frogs, located in river beach, farmland. In the process of construction, mechanical operation of the amphibian animal habitat from destruction, may also cause damage to the individual. But construction never on evaluation area amphibian animal population and the number of significant impact, therefore, during construction, through the strengthening of the construction workers of wild animal protection knowledge propaganda, careful to avoid, can prevent the amphibian animal effect.

(2) Effects on reptiles

Occupied area reptiles including snakes and lizards, animal. In the process of the construction of large machinery, transport vehicles are likely to hurt some reptiles, and forcing them to escape from the construction area . Because of the regional human activities have more frequent, wild reptile animal population distribution is relatively small; and the construction is the process of gradual development therefore, in the process of construction, the region will be moved to the outside of the region of reptiles similar habitat, not causing regional reptile population was substantially reduced.

(3) Effects on mammal

Occupied area wild mammal animal less species, including rats, bats animal. Rodents are mainly distributed in the scrub and residential area near; Vespertilionidae belongs to the carnivorous species, mainly distributed in the mountain area in the cave. The region accounted for in the national and provincial key protection wild mammal animal distribution project construction will force the regional animal to move it, but because the engineering construction area is small, and the near and the similar living environment is easy to find, disturbed animal can be found in the adjacent area to find a suitable living environment, migration path unobstructed, species number won't have big wave motion. But attention should be paid to protection, forbidden chaos catch excessive hunting of wild animal resources, ensure no damage.

(4) Effects on the birds

This project will occupy part of pond, orchard, grass and forest. During construction, engineering construction will destroy the original vegetation and habitat, leading to loss of habitat and food source, the birds, and foraging will effect. At the same time, in the construction process, frequent activities of the personnel, engineering machinery operation with the traffic will be in the regional activity of birds produce larger interference.
