The most important from among these factors are considered to be: long traditions of horticultural production in towns and suburban zones, size and absorptive power of the market estimated according to the number of non-agricultural population along with its food requirements and purchasing power, institutional forms of hothouse production functioning, size of settlement structures and dynamics of their development, dynamics and directions of spatial expansion, availability of trasport facilities from production site to sale points, and degree of air pollution in heavily urbanized and industrialized zones. Positive or negative influence of particular factors being correlated with one another determines primarily mechanisms of forming territorial systems of hothouse production in heavily urbanized areas. Pull understanding of these mechanisms provides a proper basis for planning and programming of spatial distribution and development of hothouse production in the analyzed areas.

The Luciąża river, left tributary of the Pilica river flows into the Sulejów reservoir. The average flow of the river at its mouth reaches 4,7 ms per second. The river water in the Luciąża basin is mainly used for agricultural purposes, and, first of all, for irrigation of ameliorated grassland (ca. 2,000 hectares), and for supplying fish ponds with water (ca. 150 hectares). Water requirements of the population and the industry are supplied by the underground water with about 70 per cent of all farms using shallow topsoil and alluvial waters. Water supply systems in rural, areas are few and far between. The most important tasks facing the water economy in the Luciąża river basin include: - improvement of purity of the Luciąża river and its main tributaries so that they do not impair the sanitary level of the Sulejów reservoir; - ample provision of water for agriculture and forestry, first of all for the area which is directly affected by the Bełchatów lignite mine through construction of central water supply systems based on deep intakes of the underground water and transfer of water from other river basins (the Pilica and the Widawka rivers) as well as storage of it in agricultural storage reservoirs. Bigger reservoirs should be built on the upper course of the Luciąża and the Bogdanówka. Water deficit in the Luciąźa river basin for 1985 is estimated at ca. 40-50 million cubic metres.

These changes were most dynamic in the administrative provinces of Konin and Płock in which, due to putting on stream new industrial projects, the number of population grew by 86 per cent over the period of 1946-1975. In the remaining area of Central Poland the index of urban density growth (with 1946 = 100) amounted from 153 in the province of Włocławek to 166 in those of Sieradz and Skierniewice. The economic development leads to intensification of migratory movement from villages to towns as a result of which in majority of the discussed provinces there can be observed a decline in the number of rural population reaching ca. 10 per cent in relation to 1946. The outflow of population from villages to towns produces also changes in the employment structure. In 1975 the total number of people employed outside agriculture in Central Poland exceeded 50 per cent of the overall number of the professionally active population. The trends of demographic changes as presented above exert an influence on the manpower resources economy which must be duly taken into account when drafting economic development plans for the above mentioned administrative provinces.

Enclosing within its boundaries two large urban and industrial agglomerations of Warsaw and Łódź, some industrial districts and nuclei - Central Poland constitutes an especially absorptive outlet for foodstuffs turned out in the local agriculture and food-processing plants as well. Market linkages of long tradition, systematically deepened by current co-operation between urban settlement network and rural productive areas, form an increasingly better outlined food and agriculture complex, both in spatial and structural respects. Just this kind of links makes one of specific features enabling Central Poland to be looked upon as an economic region.
