Read the following materials and answer the following questions (16 points). Gua diana River is one of the longest rivers in Iberian Peninsula, which originated in western Cuenca, Spain.

(1)A is dominated by mountains, with many canyons and great fluctuation, and water erosion is (2 points); B is dominated by flat plains (deltas) and mainly by flowing water deposits (2 points).

(2) It flows through the Mediterranean climate zone and is mainly replenished by precipitation (1); Large flow in winter, small flow in summer, and obvious seasonal variation of flow (2 points); Flowing through the subtropical zone during the ice-free period (1); Terrain difference and abundant hydropower (1 min)

(3) Most of Western Europe has a temperate maritime climate, with plenty of rain and insufficient sunshine (1); The coastal area near Iamonte has a Mediterranean climate with sufficient sunshine in summer (2 points); And it is close to the tourist destinations in western Europe. ( 1)

(4) The delta shrinks due to the decrease of sediment entering the sea (1); The decrease of nutrients in aquatic organisms and the change of water quantity into the sea lead to the change of living environment of aquatic organisms (1); The construction of the dam has affected the survival of migratory aquatic organisms, resulting in the reduction of water quantity of various aquatic organisms in the estuary (1 min).

Test analysis:

(1)A, the upper reaches of the river are dominated by mountains, with many canyons and large topographic relief, mainly by flowing water erosion; A is the lower reaches of the river (delta enters the sea), with flat terrain and mainly flowing water deposition.

(2) The illustrated area is the Mediterranean coast (Portugal, Spain) and the river is the outflow river. The hydrological characteristics of the outflow river can be analyzed from the aspects of discharge, flood season, ice age and sediment concentration. The recharge type of this river is mainly rainwater recharge. The Mediterranean climate is hot and dry in summer and mild and rainy in winter. The river has a large flow in winter and a small flow in summer, and the flow changes obviously in seasons. The monthly minimum temperature in subtropical areas is higher than 0℃, and there is no ice age; "Abundant hydropower resources" refers to large river drop, rapid water flow and abundant hydropower resources; River sediment concentration may be small (developed areas are better for environmental protection).

(3) The evaluation of tourism resources includes tourist value (including regional combination and cluster status), market distance, traffic accessibility, regional reception capacity and environmental carrying capacity. This area is in the southwest of Europe. The economically developed areas in Europe are mainly temperate maritime climate, with rainy summer and insufficient sunshine. Europeans like sunbathing, while the coastal area near Iamonte belongs to the Mediterranean climate, with plenty of sunshine in summer and small market distance.

(4) The integrity of geographical environment means that the elements of terrestrial environment do not exist and develop in isolation, but develop and change as a whole. In the landscape, they always strive to maintain harmony and unity with the overall characteristics of the environment. The change of one factor will lead to the change of other factors and even the whole environment, which has the effect of "pulling one hair and moving the whole body". The natural geographical environment is analyzed from five aspects: climate, topography, soil, vegetation and hydrology. River development includes river development (hydropower, water supply and shipping) and overall development of river basin (overall development of resources in river basin). The development given in the title is mainly to build reservoirs. After the completion of the reservoir, the river flow becomes gentle, the erosion and handling capacity is weakened, and the sediment and other substances in the area are reduced, which reduces the nutrients of aquatic organisms. Changes in the amount of water entering the sea lead to changes in the living environment of aquatic organisms. The decrease of sediment and other substances in the joint area and the decrease of sediment entering the sea lead to the shrinkage of the delta and the decrease of water area, which affects the growth of aquatic organisms; The construction of the dam has affected the survival of migratory aquatic organisms, resulting in the reduction of water quantity of various aquatic organisms in the estuary.
